Given numbers are 618, 605, 530, 625
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(618, 605) = 373890
GCD(618, 605) = ( 618 x 605 ) / 373890
= 618 / 605
= 618
Step2:
LCM(1, 530) = 530
GCD(1, 530) = ( 1 x 530 ) / 530
= 1 / 530
= 1
Step3:
LCM(1, 625) = 625
GCD(1, 625) = ( 1 x 625 ) / 625
= 1 / 625
= 1
So, Greatest Common Divisor of 618, 605, 530, 625 is 1
