Given numbers are 258, 865, 30, 578
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(258, 865) = 223170
GCD(258, 865) = ( 258 x 865 ) / 223170
= 258 / 865
= 258
Step2:
LCM(1, 30) = 30
GCD(1, 30) = ( 1 x 30 ) / 30
= 1 / 30
= 1
Step3:
LCM(1, 578) = 578
GCD(1, 578) = ( 1 x 578 ) / 578
= 1 / 578
= 1
So, Greatest Common Divisor of 258, 865, 30, 578 is 1
