Given numbers are 651, 707, 844, 686

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

Apply this formula for all numbers.

Step1:

LCM(651, 707) = 65751

GCD(651, 707) = ( 651 x 707 ) / 65751

= 651 / 707

= 651

Step2:

LCM(7, 844) = 5908

GCD(7, 844) = ( 7 x 844 ) / 5908

= 7 / 844

= 7

Step3:

LCM(1, 686) = 686

GCD(1, 686) = ( 1 x 686 ) / 686

= 1 / 686

= 1

So, Greatest Common Divisor of 651, 707, 844, 686 is 1
