Prime Factorization of 120
Factors of 120 by Division Method
The factors of 120 can be found by using division method. Divide 120 by numbers between 1 and 120, If the number divides 120 with remainder zero , then the number is a factor of 120.
120/1 = 120 ( 1 and 120 are the pair factors of 120)
120/2 = 60 ( 2 and 60 are the pair factors of 120)
120/3 = 40 ( 3 and 40 are the pair factors of 120)
120/4 = 30 ( 4 and 30 are the pair factors of 120)
120/5 = 24 ( 5 and 24 are the pair factors of 120)
120/6 = 20 ( 6 and 20 are the pair factors of 120)
120/8 = 15 ( 8 and 15 are the pair factors of 120)
120/10 = 12 ( 10 and 12 are the pair factors of 120)
120/12 = 10 ( 12 and 10 are the pair factors of 120)
120/15 = 8 ( 15 and 8 are the pair factors of 120)
120/20 = 6 ( 20 and 6 are the pair factors of 120)
120/24 = 5 ( 24 and 5 are the pair factors of 120)
120/30 = 4 ( 30 and 4 are the pair factors of 120)
120/40 = 3 ( 40 and 3 are the pair factors of 120)
120/60 = 2 ( 60 and 2 are the pair factors of 120)
120/120 = 1 ( 120 and 1 are the pair factors of 120)
If we divide 120 by any number between 1 and 120 other than 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, and 120. it gives a non-zero remainder. so they are not factors of 120.
Hence, factors of 120 are 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, and 120.
