Given numbers are 786, 687, 997, 756
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(786, 687) = 179994
GCD(786, 687) = ( 786 x 687 ) / 179994
= 786 / 687
= 786
Step2:
LCM(3, 997) = 2991
GCD(3, 997) = ( 3 x 997 ) / 2991
= 3 / 997
= 3
Step3:
LCM(1, 756) = 756
GCD(1, 756) = ( 1 x 756 ) / 756
= 1 / 756
= 1
So, Greatest Common Divisor of 786, 687, 997, 756 is 1
