Given numbers are 989, 361, 802, 251
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(989, 361) = 357029
GCD(989, 361) = ( 989 x 361 ) / 357029
= 989 / 361
= 989
Step2:
LCM(1, 802) = 802
GCD(1, 802) = ( 1 x 802 ) / 802
= 1 / 802
= 1
Step3:
LCM(1, 251) = 251
GCD(1, 251) = ( 1 x 251 ) / 251
= 1 / 251
= 1
So, Greatest Common Divisor of 989, 361, 802, 251 is 1
