GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(890, 639) = 568710
GCD(890, 639) = ( 890 x 639 ) / 568710
= 890 / 639
= 890
Step2:
LCM(1, 693) = 693
GCD(1, 693) = ( 1 x 693 ) / 693
= 1 / 693
= 1
Step3:
LCM(1, 630) = 630
GCD(1, 630) = ( 1 x 630 ) / 630
= 1 / 630
= 1
So, Greatest Common Divisor of 890, 639, 693, 630 is 1
