Given numbers are 642, 670, 24, 963

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

Apply this formula for all numbers.

Step1:

LCM(642, 670) = 215070

GCD(642, 670) = ( 642 x 670 ) / 215070

= 642 / 670

= 642

Step2:

LCM(2, 24) = 24

GCD(2, 24) = ( 2 x 24 ) / 24

= 2 / 24

= 2

Step3:

LCM(2, 963) = 1926

GCD(2, 963) = ( 2 x 963 ) / 1926

= 2 / 963

= 2

So, Greatest Common Divisor of 642, 670, 24, 963 is 1
