GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(882, 213) = 62622
GCD(882, 213) = ( 882 x 213 ) / 62622
= 882 / 213
= 882
Step2:
LCM(3, 697) = 2091
GCD(3, 697) = ( 3 x 697 ) / 2091
= 3 / 697
= 3
Step3:
LCM(1, 639) = 639
GCD(1, 639) = ( 1 x 639 ) / 639
= 1 / 639
= 1
So, Greatest Common Divisor of 882, 213, 697, 639 is 1
