GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(628, 212) = 33284
GCD(628, 212) = ( 628 x 212 ) / 33284
= 628 / 212
= 628
Step2:
LCM(4, 517) = 2068
GCD(4, 517) = ( 4 x 517 ) / 2068
= 4 / 517
= 4
Step3:
LCM(1, 918) = 918
GCD(1, 918) = ( 1 x 918 ) / 918
= 1 / 918
= 1
So, Greatest Common Divisor of 628, 212, 517, 918 is 1
