Given numbers are 247, 675, 258, 828
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(247, 675) = 166725
GCD(247, 675) = ( 247 x 675 ) / 166725
= 247 / 675
= 247
Step2:
LCM(1, 258) = 258
GCD(1, 258) = ( 1 x 258 ) / 258
= 1 / 258
= 1
Step3:
LCM(1, 828) = 828
GCD(1, 828) = ( 1 x 828 ) / 828
= 1 / 828
= 1
So, Greatest Common Divisor of 247, 675, 258, 828 is 1
