Given numbers are 687, 786, 529, 136
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(687, 786) = 179994
GCD(687, 786) = ( 687 x 786 ) / 179994
= 687 / 786
= 687
Step2:
LCM(3, 529) = 1587
GCD(3, 529) = ( 3 x 529 ) / 1587
= 3 / 529
= 3
Step3:
LCM(1, 136) = 136
GCD(1, 136) = ( 1 x 136 ) / 136
= 1 / 136
= 1
So, Greatest Common Divisor of 687, 786, 529, 136 is 1
