GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(858, 202) = 86658
GCD(858, 202) = ( 858 x 202 ) / 86658
= 858 / 202
= 858
Step2:
LCM(2, 605) = 1210
GCD(2, 605) = ( 2 x 605 ) / 1210
= 2 / 605
= 2
Step3:
LCM(1, 978) = 978
GCD(1, 978) = ( 1 x 978 ) / 978
= 1 / 978
= 1
So, Greatest Common Divisor of 858, 202, 605, 978 is 1
