Given numbers are 401, 780, 755
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(401, 780) = 312780
GCD(401, 780) = ( 401 x 780 ) / 312780
= 401 / 780
= 401
Step2:
LCM(1, 755) = 755
GCD(1, 755) = ( 1 x 755 ) / 755
= 1 / 755
= 1
So, Greatest Common Divisor of 401, 780, 755 is 1
