GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(393, 179) = 70347
GCD(393, 179) = ( 393 x 179 ) / 70347
= 393 / 179
= 393
Step2:
LCM(1, 532) = 532
GCD(1, 532) = ( 1 x 532 ) / 532
= 1 / 532
= 1
Step3:
LCM(1, 490) = 490
GCD(1, 490) = ( 1 x 490 ) / 490
= 1 / 490
= 1
So, Greatest Common Divisor of 393, 179, 532, 490 is 1
