Given numbers are 762, 687, 688, 115
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(762, 687) = 174498
GCD(762, 687) = ( 762 x 687 ) / 174498
= 762 / 687
= 762
Step2:
LCM(3, 688) = 2064
GCD(3, 688) = ( 3 x 688 ) / 2064
= 3 / 688
= 3
Step3:
LCM(1, 115) = 115
GCD(1, 115) = ( 1 x 115 ) / 115
= 1 / 115
= 1
So, Greatest Common Divisor of 762, 687, 688, 115 is 1
