Given numbers are 618, 710, 550, 643
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(618, 710) = 219390
GCD(618, 710) = ( 618 x 710 ) / 219390
= 618 / 710
= 618
Step2:
LCM(2, 550) = 550
GCD(2, 550) = ( 2 x 550 ) / 550
= 2 / 550
= 2
Step3:
LCM(2, 643) = 1286
GCD(2, 643) = ( 2 x 643 ) / 1286
= 2 / 643
= 2
So, Greatest Common Divisor of 618, 710, 550, 643 is 1
