Given numbers are 485, 390, 851, 571
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(485, 390) = 37830
GCD(485, 390) = ( 485 x 390 ) / 37830
= 485 / 390
= 485
Step2:
LCM(5, 851) = 4255
GCD(5, 851) = ( 5 x 851 ) / 4255
= 5 / 851
= 5
Step3:
LCM(1, 571) = 571
GCD(1, 571) = ( 1 x 571 ) / 571
= 1 / 571
= 1
So, Greatest Common Divisor of 485, 390, 851, 571 is 1
