Given numbers are 391, 147, 902, 637

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

Apply this formula for all numbers.

Step1:

LCM(391, 147) = 57477

GCD(391, 147) = ( 391 x 147 ) / 57477

= 391 / 147

= 391

Step2:

LCM(1, 902) = 902

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

= 1 / 902

= 1

Step3:

LCM(1, 637) = 637

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

= 1 / 637

= 1

So, Greatest Common Divisor of 391, 147, 902, 637 is 1
