GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(728, 291) = 211848
GCD(728, 291) = ( 728 x 291 ) / 211848
= 728 / 291
= 728
Step2:
LCM(1, 847) = 847
GCD(1, 847) = ( 1 x 847 ) / 847
= 1 / 847
= 1
Step3:
LCM(1, 318) = 318
GCD(1, 318) = ( 1 x 318 ) / 318
= 1 / 318
= 1
So, Greatest Common Divisor of 728, 291, 847, 318 is 1
