GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(441, 429) = 63063
GCD(441, 429) = ( 441 x 429 ) / 63063
= 441 / 429
= 441
Step2:
LCM(3, 777) = 777
GCD(3, 777) = ( 3 x 777 ) / 777
= 3 / 777
= 3
Step3:
LCM(3, 728) = 2184
GCD(3, 728) = ( 3 x 728 ) / 2184
= 3 / 728
= 3
So, Greatest Common Divisor of 441, 429, 777, 728 is 1
