GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(258, 661) = 170538
GCD(258, 661) = ( 258 x 661 ) / 170538
= 258 / 661
= 258
Step2:
LCM(1, 986) = 986
GCD(1, 986) = ( 1 x 986 ) / 986
= 1 / 986
= 1
Step3:
LCM(1, 859) = 859
GCD(1, 859) = ( 1 x 859 ) / 859
= 1 / 859
= 1
So, Greatest Common Divisor of 258, 661, 986, 859 is 1
