Given numbers are 980, 160, 639, 496
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(980, 160) = 7840
GCD(980, 160) = ( 980 x 160 ) / 7840
= 980 / 160
= 980
Step2:
LCM(20, 639) = 12780
GCD(20, 639) = ( 20 x 639 ) / 12780
= 20 / 639
= 20
Step3:
LCM(1, 496) = 496
GCD(1, 496) = ( 1 x 496 ) / 496
= 1 / 496
= 1
So, Greatest Common Divisor of 980, 160, 639, 496 is 1
