Given numbers are 771, 780, 295
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(771, 780) = 200460
GCD(771, 780) = ( 771 x 780 ) / 200460
= 771 / 780
= 771
Step2:
LCM(3, 295) = 885
GCD(3, 295) = ( 3 x 295 ) / 885
= 3 / 295
= 3
So, Greatest Common Divisor of 771, 780, 295 is 1
