Given numbers are 921, 786, 947, 651

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

Apply this formula for all numbers.

Step1:

LCM(921, 786) = 241302

GCD(921, 786) = ( 921 x 786 ) / 241302

= 921 / 786

= 921

Step2:

LCM(3, 947) = 2841

GCD(3, 947) = ( 3 x 947 ) / 2841

= 3 / 947

= 3

Step3:

LCM(1, 651) = 651

GCD(1, 651) = ( 1 x 651 ) / 651

= 1 / 651

= 1

So, Greatest Common Divisor of 921, 786, 947, 651 is 1
