Given numbers are 618, 355, 141, 390
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(618, 355) = 219390
GCD(618, 355) = ( 618 x 355 ) / 219390
= 618 / 355
= 618
Step2:
LCM(1, 141) = 141
GCD(1, 141) = ( 1 x 141 ) / 141
= 1 / 141
= 1
Step3:
LCM(1, 390) = 390
GCD(1, 390) = ( 1 x 390 ) / 390
= 1 / 390
= 1
So, Greatest Common Divisor of 618, 355, 141, 390 is 1
