Given numbers are 491, 420, 568, 503
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(491, 420) = 206220
GCD(491, 420) = ( 491 x 420 ) / 206220
= 491 / 420
= 491
Step2:
LCM(1, 568) = 568
GCD(1, 568) = ( 1 x 568 ) / 568
= 1 / 568
= 1
Step3:
LCM(1, 503) = 503
GCD(1, 503) = ( 1 x 503 ) / 503
= 1 / 503
= 1
So, Greatest Common Divisor of 491, 420, 568, 503 is 1
