Given numbers are 618, 816, 63, 291

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(618, 816) = 84048

GCD(618, 816) = ( 618 x 816 ) / 84048

= 618 / 816

= 618

Step2:

LCM(6, 63) = 126

GCD(6, 63) = ( 6 x 63 ) / 126

= 6 / 63

= 6

Step3:

LCM(3, 291) = 291

GCD(3, 291) = ( 3 x 291 ) / 291

= 3 / 291

= 3

So, Greatest Common Divisor of 618, 816, 63, 291 is 3
