GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(808, 542) = 218968
GCD(808, 542) = ( 808 x 542 ) / 218968
= 808 / 542
= 808
Step2:
LCM(2, 421) = 842
GCD(2, 421) = ( 2 x 421 ) / 842
= 2 / 421
= 2
Step3:
LCM(1, 456) = 456
GCD(1, 456) = ( 1 x 456 ) / 456
= 1 / 456
= 1
So, Greatest Common Divisor of 808, 542, 421, 456 is 1
