Given numbers are 962, 128, 946, 645

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

Apply this formula for all numbers.

Step1:

LCM(962, 128) = 61568

GCD(962, 128) = ( 962 x 128 ) / 61568

= 962 / 128

= 962

Step2:

LCM(2, 946) = 946

GCD(2, 946) = ( 2 x 946 ) / 946

= 2 / 946

= 2

Step3:

LCM(2, 645) = 1290

GCD(2, 645) = ( 2 x 645 ) / 1290

= 2 / 645

= 2

So, Greatest Common Divisor of 962, 128, 946, 645 is 1
