GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(457, 840) = 383880
GCD(457, 840) = ( 457 x 840 ) / 383880
= 457 / 840
= 457
Step2:
LCM(1, 349) = 349
GCD(1, 349) = ( 1 x 349 ) / 349
= 1 / 349
= 1
Step3:
LCM(1, 555) = 555
GCD(1, 555) = ( 1 x 555 ) / 555
= 1 / 555
= 1
So, Greatest Common Divisor of 457, 840, 349, 555 is 1
