GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(649, 783) = 508167
GCD(649, 783) = ( 649 x 783 ) / 508167
= 649 / 783
= 649
Step2:
LCM(1, 691) = 691
GCD(1, 691) = ( 1 x 691 ) / 691
= 1 / 691
= 1
Step3:
LCM(1, 379) = 379
GCD(1, 379) = ( 1 x 379 ) / 379
= 1 / 379
= 1
So, Greatest Common Divisor of 649, 783, 691, 379 is 1
