Given numbers are 656, 698, 215, 708

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

Apply this formula for all numbers.

Step1:

LCM(656, 698) = 228944

GCD(656, 698) = ( 656 x 698 ) / 228944

= 656 / 698

= 656

Step2:

LCM(2, 215) = 430

GCD(2, 215) = ( 2 x 215 ) / 430

= 2 / 215

= 2

Step3:

LCM(1, 708) = 708

GCD(1, 708) = ( 1 x 708 ) / 708

= 1 / 708

= 1

So, Greatest Common Divisor of 656, 698, 215, 708 is 1
