HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 2605, 9276, 70144 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 2605, 9276, 70144 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 2605, 9276, 70144 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 2605, 9276, 70144 is 1.
HCF(2605, 9276, 70144) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 2605, 9276, 70144 is 1.
Step 1: Since 9276 > 2605, we apply the division lemma to 9276 and 2605, to get
9276 = 2605 x 3 + 1461
Step 2: Since the reminder 2605 ≠ 0, we apply division lemma to 1461 and 2605, to get
2605 = 1461 x 1 + 1144
Step 3: We consider the new divisor 1461 and the new remainder 1144, and apply the division lemma to get
1461 = 1144 x 1 + 317
We consider the new divisor 1144 and the new remainder 317,and apply the division lemma to get
1144 = 317 x 3 + 193
We consider the new divisor 317 and the new remainder 193,and apply the division lemma to get
317 = 193 x 1 + 124
We consider the new divisor 193 and the new remainder 124,and apply the division lemma to get
193 = 124 x 1 + 69
We consider the new divisor 124 and the new remainder 69,and apply the division lemma to get
124 = 69 x 1 + 55
We consider the new divisor 69 and the new remainder 55,and apply the division lemma to get
69 = 55 x 1 + 14
We consider the new divisor 55 and the new remainder 14,and apply the division lemma to get
55 = 14 x 3 + 13
We consider the new divisor 14 and the new remainder 13,and apply the division lemma to get
14 = 13 x 1 + 1
We consider the new divisor 13 and the new remainder 1,and apply the division lemma to get
13 = 1 x 13 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 2605 and 9276 is 1
Notice that 1 = HCF(13,1) = HCF(14,13) = HCF(55,14) = HCF(69,55) = HCF(124,69) = HCF(193,124) = HCF(317,193) = HCF(1144,317) = HCF(1461,1144) = HCF(2605,1461) = HCF(9276,2605) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 70144 > 1, we apply the division lemma to 70144 and 1, to get
70144 = 1 x 70144 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 70144 is 1
Notice that 1 = HCF(70144,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
