Given numbers are 414, 170, 111, 721
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(414, 170) = 35190
GCD(414, 170) = ( 414 x 170 ) / 35190
= 414 / 170
= 414
Step2:
LCM(2, 111) = 222
GCD(2, 111) = ( 2 x 111 ) / 222
= 2 / 111
= 2
Step3:
LCM(1, 721) = 721
GCD(1, 721) = ( 1 x 721 ) / 721
= 1 / 721
= 1
So, Greatest Common Divisor of 414, 170, 111, 721 is 1
