Given numbers are 647, 421, 410, 612
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(647, 421) = 272387
GCD(647, 421) = ( 647 x 421 ) / 272387
= 647 / 421
= 647
Step2:
LCM(1, 410) = 410
GCD(1, 410) = ( 1 x 410 ) / 410
= 1 / 410
= 1
Step3:
LCM(1, 612) = 612
GCD(1, 612) = ( 1 x 612 ) / 612
= 1 / 612
= 1
So, Greatest Common Divisor of 647, 421, 410, 612 is 1
