Given numbers are 618, 132, 665, 787

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

Apply this formula for all numbers.

Step1:

LCM(618, 132) = 13596

GCD(618, 132) = ( 618 x 132 ) / 13596

= 618 / 132

= 618

Step2:

LCM(6, 665) = 3990

GCD(6, 665) = ( 6 x 665 ) / 3990

= 6 / 665

= 6

Step3:

LCM(1, 787) = 787

GCD(1, 787) = ( 1 x 787 ) / 787

= 1 / 787

= 1

So, Greatest Common Divisor of 618, 132, 665, 787 is 1
