GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(850, 578) = 14450
GCD(850, 578) = ( 850 x 578 ) / 14450
= 850 / 578
= 850
Step2:
LCM(34, 858) = 14586
GCD(34, 858) = ( 34 x 858 ) / 14586
= 34 / 858
= 34
Step3:
LCM(2, 438) = 438
GCD(2, 438) = ( 2 x 438 ) / 438
= 2 / 438
= 2
So, Greatest Common Divisor of 850, 578, 858, 438 is 2
