Given numbers are 786, 630, 257, 193

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

Apply this formula for all numbers.

Step1:

LCM(786, 630) = 82530

GCD(786, 630) = ( 786 x 630 ) / 82530

= 786 / 630

= 786

Step2:

LCM(6, 257) = 1542

GCD(6, 257) = ( 6 x 257 ) / 1542

= 6 / 257

= 6

Step3:

LCM(1, 193) = 193

GCD(1, 193) = ( 1 x 193 ) / 193

= 1 / 193

= 1

So, Greatest Common Divisor of 786, 630, 257, 193 is 1
