Find GCD of 12, 76, 66, 63 using Prime Factorization

Given numbers are 12, 76, 66, 63

The list of prime factors of all numbers are

Prime factors of 12 are 2 x 2 x 3

Prime factors of 76 are 2 x 2 x 19

Prime factors of 66 are 2 x 3 x 11

Prime factors of 63 are 3 x 3 x 7

The above numbers do not have any common prime factor. So GCD is 1

Steps to Calculate GCD of 12, 76, 66, 63 using LCM Formula

Given numbers are 12, 76, 66, 63

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(12, 76) = 228

GCD(12, 76) = ( 12 x 76 ) / 228

= 12 / 76

= 12


Step2:

LCM(4, 66) = 132

GCD(4, 66) = ( 4 x 66 ) / 132

= 4 / 66

= 4


Step3:

LCM(2, 63) = 126

GCD(2, 63) = ( 2 x 63 ) / 126

= 2 / 63

= 2


So, Greatest Common Divisor of 12, 76, 66, 63 is 1
