Given numbers are 355, 780, 929, 389
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(355, 780) = 55380
GCD(355, 780) = ( 355 x 780 ) / 55380
= 355 / 780
= 355
Step2:
LCM(5, 929) = 4645
GCD(5, 929) = ( 5 x 929 ) / 4645
= 5 / 929
= 5
Step3:
LCM(1, 389) = 389
GCD(1, 389) = ( 1 x 389 ) / 389
= 1 / 389
= 1
So, Greatest Common Divisor of 355, 780, 929, 389 is 1
