Given numbers are 407, 770, 137, 637

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

Apply this formula for all numbers.

Step1:

LCM(407, 770) = 28490

GCD(407, 770) = ( 407 x 770 ) / 28490

= 407 / 770

= 407

Step2:

LCM(11, 137) = 1507

GCD(11, 137) = ( 11 x 137 ) / 1507

= 11 / 137

= 11

Step3:

LCM(1, 637) = 637

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

= 1 / 637

= 1

So, Greatest Common Divisor of 407, 770, 137, 637 is 1
