GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(519, 397) = 206043
GCD(519, 397) = ( 519 x 397 ) / 206043
= 519 / 397
= 519
Step2:
LCM(1, 330) = 330
GCD(1, 330) = ( 1 x 330 ) / 330
= 1 / 330
= 1
Step3:
LCM(1, 639) = 639
GCD(1, 639) = ( 1 x 639 ) / 639
= 1 / 639
= 1
So, Greatest Common Divisor of 519, 397, 330, 639 is 1
