GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(856, 530) = 226840
GCD(856, 530) = ( 856 x 530 ) / 226840
= 856 / 530
= 856
Step2:
LCM(2, 646) = 646
GCD(2, 646) = ( 2 x 646 ) / 646
= 2 / 646
= 2
Step3:
LCM(2, 258) = 258
GCD(2, 258) = ( 2 x 258 ) / 258
= 2 / 258
= 2
So, Greatest Common Divisor of 856, 530, 646, 258 is 2
