Given numbers are 621, 987, 458, 464

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

Apply this formula for all numbers.

Step1:

LCM(621, 987) = 204309

GCD(621, 987) = ( 621 x 987 ) / 204309

= 621 / 987

= 621

Step2:

LCM(3, 458) = 1374

GCD(3, 458) = ( 3 x 458 ) / 1374

= 3 / 458

= 3

Step3:

LCM(1, 464) = 464

GCD(1, 464) = ( 1 x 464 ) / 464

= 1 / 464

= 1

So, Greatest Common Divisor of 621, 987, 458, 464 is 1
