Given numbers are 491, 421, 363, 392
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(491, 421) = 206711
GCD(491, 421) = ( 491 x 421 ) / 206711
= 491 / 421
= 491
Step2:
LCM(1, 363) = 363
GCD(1, 363) = ( 1 x 363 ) / 363
= 1 / 363
= 1
Step3:
LCM(1, 392) = 392
GCD(1, 392) = ( 1 x 392 ) / 392
= 1 / 392
= 1
So, Greatest Common Divisor of 491, 421, 363, 392 is 1
