Given numbers are 217, 854, 78, 964

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

Apply this formula for all numbers.

Step1:

LCM(217, 854) = 26474

GCD(217, 854) = ( 217 x 854 ) / 26474

= 217 / 854

= 217

Step2:

LCM(7, 78) = 546

GCD(7, 78) = ( 7 x 78 ) / 546

= 7 / 78

= 7

Step3:

LCM(1, 964) = 964

GCD(1, 964) = ( 1 x 964 ) / 964

= 1 / 964

= 1

So, Greatest Common Divisor of 217, 854, 78, 964 is 1
