Given numbers are 555, 125, 815, 147
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(555, 125) = 13875
GCD(555, 125) = ( 555 x 125 ) / 13875
= 555 / 125
= 555
Step2:
LCM(5, 815) = 815
GCD(5, 815) = ( 5 x 815 ) / 815
= 5 / 815
= 5
Step3:
LCM(5, 147) = 735
GCD(5, 147) = ( 5 x 147 ) / 735
= 5 / 147
= 5
So, Greatest Common Divisor of 555, 125, 815, 147 is 1
