Given numbers are 406, 357, 220, 556
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(406, 357) = 20706
GCD(406, 357) = ( 406 x 357 ) / 20706
= 406 / 357
= 406
Step2:
LCM(7, 220) = 1540
GCD(7, 220) = ( 7 x 220 ) / 1540
= 7 / 220
= 7
Step3:
LCM(1, 556) = 556
GCD(1, 556) = ( 1 x 556 ) / 556
= 1 / 556
= 1
So, Greatest Common Divisor of 406, 357, 220, 556 is 1
