Given numbers are 658, 128, 506, 137

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

Apply this formula for all numbers.

Step1:

LCM(658, 128) = 42112

GCD(658, 128) = ( 658 x 128 ) / 42112

= 658 / 128

= 658

Step2:

LCM(2, 506) = 506

GCD(2, 506) = ( 2 x 506 ) / 506

= 2 / 506

= 2

Step3:

LCM(2, 137) = 274

GCD(2, 137) = ( 2 x 137 ) / 274

= 2 / 137

= 2

So, Greatest Common Divisor of 658, 128, 506, 137 is 1
