Given numbers are 166, 728, 328, 815
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(166, 728) = 60424
GCD(166, 728) = ( 166 x 728 ) / 60424
= 166 / 728
= 166
Step2:
LCM(2, 328) = 328
GCD(2, 328) = ( 2 x 328 ) / 328
= 2 / 328
= 2
Step3:
LCM(2, 815) = 1630
GCD(2, 815) = ( 2 x 815 ) / 1630
= 2 / 815
= 2
So, Greatest Common Divisor of 166, 728, 328, 815 is 1
