HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 388, 2605 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 388, 2605 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.
Consider we have numbers 388, 2605 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b
Highest common factor (HCF) of 388, 2605 is 1.
HCF(388, 2605) = 1
HCF of 388, 2605 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 388, 2605 is 1.
Highest Common Factor of 388,2605 is 1
Step 1: Since 2605 > 388, we apply the division lemma to 2605 and 388, to get
2605 = 388 x 6 + 277
Step 2: Since the reminder 388 ≠ 0, we apply division lemma to 277 and 388, to get
388 = 277 x 1 + 111
Step 3: We consider the new divisor 277 and the new remainder 111, and apply the division lemma to get
277 = 111 x 2 + 55
We consider the new divisor 111 and the new remainder 55,and apply the division lemma to get
111 = 55 x 2 + 1
We consider the new divisor 55 and the new remainder 1,and apply the division lemma to get
55 = 1 x 55 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 388 and 2605 is 1
Notice that 1 = HCF(55,1) = HCF(111,55) = HCF(277,111) = HCF(388,277) = HCF(2605,388) .
