GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(647, 874) = 565478
GCD(647, 874) = ( 647 x 874 ) / 565478
= 647 / 874
= 647
Step2:
LCM(1, 607) = 607
GCD(1, 607) = ( 1 x 607 ) / 607
= 1 / 607
= 1
Step3:
LCM(1, 278) = 278
GCD(1, 278) = ( 1 x 278 ) / 278
= 1 / 278
= 1
So, Greatest Common Divisor of 647, 874, 607, 278 is 1
