Given numbers are 680, 378, 67, 137

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

Apply this formula for all numbers.

Step1:

LCM(680, 378) = 128520

GCD(680, 378) = ( 680 x 378 ) / 128520

= 680 / 378

= 680

Step2:

LCM(2, 67) = 134

GCD(2, 67) = ( 2 x 67 ) / 134

= 2 / 67

= 2

Step3:

LCM(1, 137) = 137

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

= 1 / 137

= 1

So, Greatest Common Divisor of 680, 378, 67, 137 is 1
