Given numbers are 315, 868, 647, 892

The list of prime factors of all numbers are

Prime factors of 315 are 3 x 3 x 5 x 7

Prime factors of 868 are 2 x 2 x 7 x 31

Prime factors of 647 are 647

Prime factors of 892 are 2 x 2 x 223

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

Given numbers are 315, 868, 647, 892

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

Apply this formula for all numbers.

Step1:

LCM(315, 868) = 39060

GCD(315, 868) = ( 315 x 868 ) / 39060

= 315 / 868

= 315

Step2:

LCM(7, 647) = 4529

GCD(7, 647) = ( 7 x 647 ) / 4529

= 7 / 647

= 7

Step3:

LCM(1, 892) = 892

GCD(1, 892) = ( 1 x 892 ) / 892

= 1 / 892

= 1

So, Greatest Common Divisor of 315, 868, 647, 892 is 1
