Given numbers are 154, 581, 220, 579
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(154, 581) = 12782
GCD(154, 581) = ( 154 x 581 ) / 12782
= 154 / 581
= 154
Step2:
LCM(7, 220) = 1540
GCD(7, 220) = ( 7 x 220 ) / 1540
= 7 / 220
= 7
Step3:
LCM(1, 579) = 579
GCD(1, 579) = ( 1 x 579 ) / 579
= 1 / 579
= 1
So, Greatest Common Divisor of 154, 581, 220, 579 is 1
