Given numbers are 399, 532, 980, 493
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(399, 532) = 1596
GCD(399, 532) = ( 399 x 532 ) / 1596
= 399 / 532
= 399
Step2:
LCM(133, 980) = 18620
GCD(133, 980) = ( 133 x 980 ) / 18620
= 133 / 980
= 133
Step3:
LCM(7, 493) = 3451
GCD(7, 493) = ( 7 x 493 ) / 3451
= 7 / 493
= 7
So, Greatest Common Divisor of 399, 532, 980, 493 is 1
