Given numbers are 520, 417, 145
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(520, 417) = 216840
GCD(520, 417) = ( 520 x 417 ) / 216840
= 520 / 417
= 520
Step2:
LCM(1, 145) = 145
GCD(1, 145) = ( 1 x 145 ) / 145
= 1 / 145
= 1
So, Greatest Common Divisor of 520, 417, 145 is 1
