Given numbers are 258, 770, 401, 144
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(258, 770) = 99330
GCD(258, 770) = ( 258 x 770 ) / 99330
= 258 / 770
= 258
Step2:
LCM(2, 401) = 802
GCD(2, 401) = ( 2 x 401 ) / 802
= 2 / 401
= 2
Step3:
LCM(1, 144) = 144
GCD(1, 144) = ( 1 x 144 ) / 144
= 1 / 144
= 1
So, Greatest Common Divisor of 258, 770, 401, 144 is 1
