Given numbers are 643, 280, 831, 579
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(643, 280) = 180040
GCD(643, 280) = ( 643 x 280 ) / 180040
= 643 / 280
= 643
Step2:
LCM(1, 831) = 831
GCD(1, 831) = ( 1 x 831 ) / 831
= 1 / 831
= 1
Step3:
LCM(1, 579) = 579
GCD(1, 579) = ( 1 x 579 ) / 579
= 1 / 579
= 1
So, Greatest Common Divisor of 643, 280, 831, 579 is 1
