Given numbers are 872, 690, 761, 162

The list of prime factors of all numbers are

Prime factors of 872 are 2 x 2 x 2 x 109

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

Prime factors of 761 are 761

Prime factors of 162 are 2 x 3 x 3 x 3 x 3

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

Given numbers are 872, 690, 761, 162

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

Apply this formula for all numbers.

Step1:

LCM(872, 690) = 300840

GCD(872, 690) = ( 872 x 690 ) / 300840

= 872 / 690

= 872

Step2:

LCM(2, 761) = 1522

GCD(2, 761) = ( 2 x 761 ) / 1522

= 2 / 761

= 2

Step3:

LCM(1, 162) = 162

GCD(1, 162) = ( 1 x 162 ) / 162

= 1 / 162

= 1

So, Greatest Common Divisor of 872, 690, 761, 162 is 1
