GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(409, 820) = 335380
GCD(409, 820) = ( 409 x 820 ) / 335380
= 409 / 820
= 409
Step2:
LCM(1, 196) = 196
GCD(1, 196) = ( 1 x 196 ) / 196
= 1 / 196
= 1
Step3:
LCM(1, 258) = 258
GCD(1, 258) = ( 1 x 258 ) / 258
= 1 / 258
= 1
So, Greatest Common Divisor of 409, 820, 196, 258 is 1
