Given numbers are 989, 858, 250, 620
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(989, 858) = 848562
GCD(989, 858) = ( 989 x 858 ) / 848562
= 989 / 858
= 989
Step2:
LCM(1, 250) = 250
GCD(1, 250) = ( 1 x 250 ) / 250
= 1 / 250
= 1
Step3:
LCM(1, 620) = 620
GCD(1, 620) = ( 1 x 620 ) / 620
= 1 / 620
= 1
So, Greatest Common Divisor of 989, 858, 250, 620 is 1
