Given numbers are 618, 531, 421, 761
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(618, 531) = 109386
GCD(618, 531) = ( 618 x 531 ) / 109386
= 618 / 531
= 618
Step2:
LCM(3, 421) = 1263
GCD(3, 421) = ( 3 x 421 ) / 1263
= 3 / 421
= 3
Step3:
LCM(1, 761) = 761
GCD(1, 761) = ( 1 x 761 ) / 761
= 1 / 761
= 1
So, Greatest Common Divisor of 618, 531, 421, 761 is 1
