Given numbers are 707, 643, 280

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

Apply this formula for all numbers.

Step1:

LCM(707, 643) = 454601

GCD(707, 643) = ( 707 x 643 ) / 454601

= 707 / 643

= 707

Step2:

LCM(1, 280) = 280

GCD(1, 280) = ( 1 x 280 ) / 280

= 1 / 280

= 1

So, Greatest Common Divisor of 707, 643, 280 is 1
