GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(771, 450) = 115650
GCD(771, 450) = ( 771 x 450 ) / 115650
= 771 / 450
= 771
Step2:
LCM(3, 121) = 363
GCD(3, 121) = ( 3 x 121 ) / 363
= 3 / 121
= 3
So, Greatest Common Divisor of 771, 450, 121 is 1
