Given numbers are 876, 690, 126, 661

The list of prime factors of all numbers are

Prime factors of 876 are 2 x 2 x 3 x 73

Prime factors of 690 are 2 x 3 x 5 x 23

Prime factors of 126 are 2 x 3 x 3 x 7

Prime factors of 661 are 661

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

Given numbers are 876, 690, 126, 661

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

Apply this formula for all numbers.

Step1:

LCM(876, 690) = 100740

GCD(876, 690) = ( 876 x 690 ) / 100740

= 876 / 690

= 876

Step2:

LCM(6, 126) = 126

GCD(6, 126) = ( 6 x 126 ) / 126

= 6 / 126

= 6

Step3:

LCM(6, 661) = 3966

GCD(6, 661) = ( 6 x 661 ) / 3966

= 6 / 661

= 6

So, Greatest Common Divisor of 876, 690, 126, 661 is 1
