Given numbers are 399, 556, 619, 986
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(399, 556) = 221844
GCD(399, 556) = ( 399 x 556 ) / 221844
= 399 / 556
= 399
Step2:
LCM(1, 619) = 619
GCD(1, 619) = ( 1 x 619 ) / 619
= 1 / 619
= 1
Step3:
LCM(1, 986) = 986
GCD(1, 986) = ( 1 x 986 ) / 986
= 1 / 986
= 1
So, Greatest Common Divisor of 399, 556, 619, 986 is 1
