Given numbers are 688, 124, 776, 153

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

Apply this formula for all numbers.

Step1:

LCM(688, 124) = 21328

GCD(688, 124) = ( 688 x 124 ) / 21328

= 688 / 124

= 688

Step2:

LCM(4, 776) = 776

GCD(4, 776) = ( 4 x 776 ) / 776

= 4 / 776

= 4

Step3:

LCM(4, 153) = 612

GCD(4, 153) = ( 4 x 153 ) / 612

= 4 / 153

= 4

So, Greatest Common Divisor of 688, 124, 776, 153 is 1
