Given numbers are 624, 666, 21, 977

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

Apply this formula for all numbers.

Step1:

LCM(624, 666) = 69264

GCD(624, 666) = ( 624 x 666 ) / 69264

= 624 / 666

= 624

Step2:

LCM(6, 21) = 42

GCD(6, 21) = ( 6 x 21 ) / 42

= 6 / 21

= 6

Step3:

LCM(3, 977) = 2931

GCD(3, 977) = ( 3 x 977 ) / 2931

= 3 / 977

= 3

So, Greatest Common Divisor of 624, 666, 21, 977 is 1
