GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(490, 775) = 75950
GCD(490, 775) = ( 490 x 775 ) / 75950
= 490 / 775
= 490
Step2:
LCM(5, 858) = 4290
GCD(5, 858) = ( 5 x 858 ) / 4290
= 5 / 858
= 5
Step3:
LCM(1, 838) = 838
GCD(1, 838) = ( 1 x 838 ) / 838
= 1 / 838
= 1
So, Greatest Common Divisor of 490, 775, 858, 838 is 1
