Given numbers are 721, 286, 144, 503
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(721, 286) = 206206
GCD(721, 286) = ( 721 x 286 ) / 206206
= 721 / 286
= 721
Step2:
LCM(1, 144) = 144
GCD(1, 144) = ( 1 x 144 ) / 144
= 1 / 144
= 1
Step3:
LCM(1, 503) = 503
GCD(1, 503) = ( 1 x 503 ) / 503
= 1 / 503
= 1
So, Greatest Common Divisor of 721, 286, 144, 503 is 1
