Given numbers are 660, 280, 299, 890
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(660, 280) = 9240
GCD(660, 280) = ( 660 x 280 ) / 9240
= 660 / 280
= 660
Step2:
LCM(20, 299) = 5980
GCD(20, 299) = ( 20 x 299 ) / 5980
= 20 / 299
= 20
Step3:
LCM(1, 890) = 890
GCD(1, 890) = ( 1 x 890 ) / 890
= 1 / 890
= 1
So, Greatest Common Divisor of 660, 280, 299, 890 is 1
