Given numbers are 128, 159, 652, 815
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(128, 159) = 20352
GCD(128, 159) = ( 128 x 159 ) / 20352
= 128 / 159
= 128
Step2:
LCM(1, 652) = 652
GCD(1, 652) = ( 1 x 652 ) / 652
= 1 / 652
= 1
Step3:
LCM(1, 815) = 815
GCD(1, 815) = ( 1 x 815 ) / 815
= 1 / 815
= 1
So, Greatest Common Divisor of 128, 159, 652, 815 is 1
