Given numbers are 240, 963, 215, 721
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(240, 963) = 77040
GCD(240, 963) = ( 240 x 963 ) / 77040
= 240 / 963
= 240
Step2:
LCM(3, 215) = 645
GCD(3, 215) = ( 3 x 215 ) / 645
= 3 / 215
= 3
Step3:
LCM(1, 721) = 721
GCD(1, 721) = ( 1 x 721 ) / 721
= 1 / 721
= 1
So, Greatest Common Divisor of 240, 963, 215, 721 is 1
