Given numbers are 670, 686, 277, 137

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

Apply this formula for all numbers.

Step1:

LCM(670, 686) = 229810

GCD(670, 686) = ( 670 x 686 ) / 229810

= 670 / 686

= 670

Step2:

LCM(2, 277) = 554

GCD(2, 277) = ( 2 x 277 ) / 554

= 2 / 277

= 2

Step3:

LCM(1, 137) = 137

GCD(1, 137) = ( 1 x 137 ) / 137

= 1 / 137

= 1

So, Greatest Common Divisor of 670, 686, 277, 137 is 1
