GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(455, 986) = 448630
GCD(455, 986) = ( 455 x 986 ) / 448630
= 455 / 986
= 455
Step2:
LCM(1, 888) = 888
GCD(1, 888) = ( 1 x 888 ) / 888
= 1 / 888
= 1
Step3:
LCM(1, 490) = 490
GCD(1, 490) = ( 1 x 490 ) / 490
= 1 / 490
= 1
So, Greatest Common Divisor of 455, 986, 888, 490 is 1
