HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 315, 79657 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 315, 79657 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 315, 79657 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 315, 79657 is 1.
HCF(315, 79657) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 315, 79657 is 1.
Step 1: Since 79657 > 315, we apply the division lemma to 79657 and 315, to get
79657 = 315 x 252 + 277
Step 2: Since the reminder 315 ≠ 0, we apply division lemma to 277 and 315, to get
315 = 277 x 1 + 38
Step 3: We consider the new divisor 277 and the new remainder 38, and apply the division lemma to get
277 = 38 x 7 + 11
We consider the new divisor 38 and the new remainder 11,and apply the division lemma to get
38 = 11 x 3 + 5
We consider the new divisor 11 and the new remainder 5,and apply the division lemma to get
11 = 5 x 2 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 315 and 79657 is 1
Notice that 1 = HCF(5,1) = HCF(11,5) = HCF(38,11) = HCF(277,38) = HCF(315,277) = HCF(79657,315) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
