Given numbers are 620, 550, 656, 351
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(620, 550) = 34100
GCD(620, 550) = ( 620 x 550 ) / 34100
= 620 / 550
= 620
Step2:
LCM(10, 656) = 3280
GCD(10, 656) = ( 10 x 656 ) / 3280
= 10 / 656
= 10
Step3:
LCM(2, 351) = 702
GCD(2, 351) = ( 2 x 351 ) / 702
= 2 / 351
= 2
So, Greatest Common Divisor of 620, 550, 656, 351 is 1
