Given numbers are 636, 618, 515, 470
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(636, 618) = 65508
GCD(636, 618) = ( 636 x 618 ) / 65508
= 636 / 618
= 636
Step2:
LCM(6, 515) = 3090
GCD(6, 515) = ( 6 x 515 ) / 3090
= 6 / 515
= 6
Step3:
LCM(1, 470) = 470
GCD(1, 470) = ( 1 x 470 ) / 470
= 1 / 470
= 1
So, Greatest Common Divisor of 636, 618, 515, 470 is 1
