Given numbers are 649, 421, 766, 815
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(649, 421) = 273229
GCD(649, 421) = ( 649 x 421 ) / 273229
= 649 / 421
= 649
Step2:
LCM(1, 766) = 766
GCD(1, 766) = ( 1 x 766 ) / 766
= 1 / 766
= 1
Step3:
LCM(1, 815) = 815
GCD(1, 815) = ( 1 x 815 ) / 815
= 1 / 815
= 1
So, Greatest Common Divisor of 649, 421, 766, 815 is 1
