Given numbers are 479, 605, 521, 155
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(479, 605) = 289795
GCD(479, 605) = ( 479 x 605 ) / 289795
= 479 / 605
= 479
Step2:
LCM(1, 521) = 521
GCD(1, 521) = ( 1 x 521 ) / 521
= 1 / 521
= 1
Step3:
LCM(1, 155) = 155
GCD(1, 155) = ( 1 x 155 ) / 155
= 1 / 155
= 1
So, Greatest Common Divisor of 479, 605, 521, 155 is 1
