GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(688, 632) = 54352
GCD(688, 632) = ( 688 x 632 ) / 54352
= 688 / 632
= 688
Step2:
LCM(8, 388) = 776
GCD(8, 388) = ( 8 x 388 ) / 776
= 8 / 388
= 8
Step3:
LCM(4, 136) = 136
GCD(4, 136) = ( 4 x 136 ) / 136
= 4 / 136
= 4
So, Greatest Common Divisor of 688, 632, 388, 136 is 4
