Given numbers are 351, 644, 389, 740
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(351, 644) = 226044
GCD(351, 644) = ( 351 x 644 ) / 226044
= 351 / 644
= 351
Step2:
LCM(1, 389) = 389
GCD(1, 389) = ( 1 x 389 ) / 389
= 1 / 389
= 1
Step3:
LCM(1, 740) = 740
GCD(1, 740) = ( 1 x 740 ) / 740
= 1 / 740
= 1
So, Greatest Common Divisor of 351, 644, 389, 740 is 1
