Given numbers are 420, 935, 998, 980
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(420, 935) = 78540
GCD(420, 935) = ( 420 x 935 ) / 78540
= 420 / 935
= 420
Step2:
LCM(5, 998) = 4990
GCD(5, 998) = ( 5 x 998 ) / 4990
= 5 / 998
= 5
Step3:
LCM(1, 980) = 980
GCD(1, 980) = ( 1 x 980 ) / 980
= 1 / 980
= 1
So, Greatest Common Divisor of 420, 935, 998, 980 is 1
