GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(428, 424) = 45368
GCD(428, 424) = ( 428 x 424 ) / 45368
= 428 / 424
= 428
Step2:
LCM(4, 858) = 1716
GCD(4, 858) = ( 4 x 858 ) / 1716
= 4 / 858
= 4
Step3:
LCM(2, 579) = 1158
GCD(2, 579) = ( 2 x 579 ) / 1158
= 2 / 579
= 2
So, Greatest Common Divisor of 428, 424, 858, 579 is 1
