GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(258, 820) = 105780
GCD(258, 820) = ( 258 x 820 ) / 105780
= 258 / 820
= 258
Step2:
LCM(2, 296) = 296
GCD(2, 296) = ( 2 x 296 ) / 296
= 2 / 296
= 2
Step3:
LCM(2, 490) = 490
GCD(2, 490) = ( 2 x 490 ) / 490
= 2 / 490
= 2
So, Greatest Common Divisor of 258, 820, 296, 490 is 2
