GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(639, 989) = 631971
GCD(639, 989) = ( 639 x 989 ) / 631971
= 639 / 989
= 639
Step2:
LCM(1, 244) = 244
GCD(1, 244) = ( 1 x 244 ) / 244
= 1 / 244
= 1
Step3:
LCM(1, 579) = 579
GCD(1, 579) = ( 1 x 579 ) / 579
= 1 / 579
= 1
So, Greatest Common Divisor of 639, 989, 244, 579 is 1
