GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(988, 902) = 445588
GCD(988, 902) = ( 988 x 902 ) / 445588
= 988 / 902
= 988
Step2:
LCM(2, 875) = 1750
GCD(2, 875) = ( 2 x 875 ) / 1750
= 2 / 875
= 2
Step3:
LCM(1, 639) = 639
GCD(1, 639) = ( 1 x 639 ) / 639
= 1 / 639
= 1
So, Greatest Common Divisor of 988, 902, 875, 639 is 1
