Given numbers are 217, 763, 610, 688

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

Apply this formula for all numbers.

Step1:

LCM(217, 763) = 23653

GCD(217, 763) = ( 217 x 763 ) / 23653

= 217 / 763

= 217

Step2:

LCM(7, 610) = 4270

GCD(7, 610) = ( 7 x 610 ) / 4270

= 7 / 610

= 7

Step3:

LCM(1, 688) = 688

GCD(1, 688) = ( 1 x 688 ) / 688

= 1 / 688

= 1

So, Greatest Common Divisor of 217, 763, 610, 688 is 1
