Given numbers are 420, 793, 802
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(420, 793) = 333060
GCD(420, 793) = ( 420 x 793 ) / 333060
= 420 / 793
= 420
Step2:
LCM(1, 802) = 802
GCD(1, 802) = ( 1 x 802 ) / 802
= 1 / 802
= 1
So, Greatest Common Divisor of 420, 793, 802 is 1
