Given numbers are 651, 391, 626, 655

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

Apply this formula for all numbers.

Step1:

LCM(651, 391) = 254541

GCD(651, 391) = ( 651 x 391 ) / 254541

= 651 / 391

= 651

Step2:

LCM(1, 626) = 626

GCD(1, 626) = ( 1 x 626 ) / 626

= 1 / 626

= 1

Step3:

LCM(1, 655) = 655

GCD(1, 655) = ( 1 x 655 ) / 655

= 1 / 655

= 1

So, Greatest Common Divisor of 651, 391, 626, 655 is 1
