GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(515, 749) = 385735
GCD(515, 749) = ( 515 x 749 ) / 385735
= 515 / 749
= 515
Step2:
LCM(1, 327) = 327
GCD(1, 327) = ( 1 x 327 ) / 327
= 1 / 327
= 1
Step3:
LCM(1, 280) = 280
GCD(1, 280) = ( 1 x 280 ) / 280
= 1 / 280
= 1
So, Greatest Common Divisor of 515, 749, 327, 280 is 1
