Given numbers are 618, 393, 569, 505
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(618, 393) = 80958
GCD(618, 393) = ( 618 x 393 ) / 80958
= 618 / 393
= 618
Step2:
LCM(3, 569) = 1707
GCD(3, 569) = ( 3 x 569 ) / 1707
= 3 / 569
= 3
Step3:
LCM(1, 505) = 505
GCD(1, 505) = ( 1 x 505 ) / 505
= 1 / 505
= 1
So, Greatest Common Divisor of 618, 393, 569, 505 is 1
