GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(399, 475) = 9975
GCD(399, 475) = ( 399 x 475 ) / 9975
= 399 / 475
= 399
Step2:
LCM(19, 989) = 18791
GCD(19, 989) = ( 19 x 989 ) / 18791
= 19 / 989
= 19
Step3:
LCM(1, 783) = 783
GCD(1, 783) = ( 1 x 783 ) / 783
= 1 / 783
= 1
So, Greatest Common Divisor of 399, 475, 989, 783 is 1
