Given numbers are 651, 647, 902, 509

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

Apply this formula for all numbers.

Step1:

LCM(651, 647) = 421197

GCD(651, 647) = ( 651 x 647 ) / 421197

= 651 / 647

= 651

Step2:

LCM(1, 902) = 902

GCD(1, 902) = ( 1 x 902 ) / 902

= 1 / 902

= 1

Step3:

LCM(1, 509) = 509

GCD(1, 509) = ( 1 x 509 ) / 509

= 1 / 509

= 1

So, Greatest Common Divisor of 651, 647, 902, 509 is 1
