Given numbers are 647, 166, 609, 617
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(647, 166) = 107402
GCD(647, 166) = ( 647 x 166 ) / 107402
= 647 / 166
= 647
Step2:
LCM(1, 609) = 609
GCD(1, 609) = ( 1 x 609 ) / 609
= 1 / 609
= 1
Step3:
LCM(1, 617) = 617
GCD(1, 617) = ( 1 x 617 ) / 617
= 1 / 617
= 1
So, Greatest Common Divisor of 647, 166, 609, 617 is 1
