GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(742, 410) = 152110
GCD(742, 410) = ( 742 x 410 ) / 152110
= 742 / 410
= 742
Step2:
LCM(2, 234) = 234
GCD(2, 234) = ( 2 x 234 ) / 234
= 2 / 234
= 2
Step3:
LCM(2, 780) = 780
GCD(2, 780) = ( 2 x 780 ) / 780
= 2 / 780
= 2
So, Greatest Common Divisor of 742, 410, 234, 780 is 2
