Given numbers are 715, 690, 807, 637

The list of prime factors of all numbers are

Prime factors of 715 are 5 x 11 x 13

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

Prime factors of 807 are 3 x 269

Prime factors of 637 are 7 x 7 x 13

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

Given numbers are 715, 690, 807, 637

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

Apply this formula for all numbers.

Step1:

LCM(715, 690) = 98670

GCD(715, 690) = ( 715 x 690 ) / 98670

= 715 / 690

= 715

Step2:

LCM(5, 807) = 4035

GCD(5, 807) = ( 5 x 807 ) / 4035

= 5 / 807

= 5

Step3:

LCM(1, 637) = 637

GCD(1, 637) = ( 1 x 637 ) / 637

= 1 / 637

= 1

So, Greatest Common Divisor of 715, 690, 807, 637 is 1
