Given numbers are 642, 117, 782, 228

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

Apply this formula for all numbers.

Step1:

LCM(642, 117) = 25038

GCD(642, 117) = ( 642 x 117 ) / 25038

= 642 / 117

= 642

Step2:

LCM(3, 782) = 2346

GCD(3, 782) = ( 3 x 782 ) / 2346

= 3 / 782

= 3

Step3:

LCM(1, 228) = 228

GCD(1, 228) = ( 1 x 228 ) / 228

= 1 / 228

= 1

So, Greatest Common Divisor of 642, 117, 782, 228 is 1
