Given numbers are 638, 521, 491, 369
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(638, 521) = 332398
GCD(638, 521) = ( 638 x 521 ) / 332398
= 638 / 521
= 638
Step2:
LCM(1, 491) = 491
GCD(1, 491) = ( 1 x 491 ) / 491
= 1 / 491
= 1
Step3:
LCM(1, 369) = 369
GCD(1, 369) = ( 1 x 369 ) / 369
= 1 / 369
= 1
So, Greatest Common Divisor of 638, 521, 491, 369 is 1
