Given numbers are 488, 386, 491, 521
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(488, 386) = 94184
GCD(488, 386) = ( 488 x 386 ) / 94184
= 488 / 386
= 488
Step2:
LCM(2, 491) = 982
GCD(2, 491) = ( 2 x 491 ) / 982
= 2 / 491
= 2
Step3:
LCM(1, 521) = 521
GCD(1, 521) = ( 1 x 521 ) / 521
= 1 / 521
= 1
So, Greatest Common Divisor of 488, 386, 491, 521 is 1
