Given numbers are 721, 906, 387, 235
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(721, 906) = 653226
GCD(721, 906) = ( 721 x 906 ) / 653226
= 721 / 906
= 721
Step2:
LCM(1, 387) = 387
GCD(1, 387) = ( 1 x 387 ) / 387
= 1 / 387
= 1
Step3:
LCM(1, 235) = 235
GCD(1, 235) = ( 1 x 235 ) / 235
= 1 / 235
= 1
So, Greatest Common Divisor of 721, 906, 387, 235 is 1
