Given numbers are 620, 421, 272
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(620, 421) = 261020
GCD(620, 421) = ( 620 x 421 ) / 261020
= 620 / 421
= 620
Step2:
LCM(1, 272) = 272
GCD(1, 272) = ( 1 x 272 ) / 272
= 1 / 272
= 1
So, Greatest Common Divisor of 620, 421, 272 is 1
