GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(149, 392) = 58408
GCD(149, 392) = ( 149 x 392 ) / 58408
= 149 / 392
= 149
Step2:
LCM(1, 517) = 517
GCD(1, 517) = ( 1 x 517 ) / 517
= 1 / 517
= 1
Step3:
LCM(1, 778) = 778
GCD(1, 778) = ( 1 x 778 ) / 778
= 1 / 778
= 1
So, Greatest Common Divisor of 149, 392, 517, 778 is 1
