Given numbers are 786, 394, 963, 220

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

Apply this formula for all numbers.

Step1:

LCM(786, 394) = 154842

GCD(786, 394) = ( 786 x 394 ) / 154842

= 786 / 394

= 786

Step2:

LCM(2, 963) = 1926

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

= 2 / 963

= 2

Step3:

LCM(1, 220) = 220

GCD(1, 220) = ( 1 x 220 ) / 220

= 1 / 220

= 1

So, Greatest Common Divisor of 786, 394, 963, 220 is 1
