HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 561, 8045 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 561, 8045 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 561, 8045 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 561, 8045 is 1.
HCF(561, 8045) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 561, 8045 is 1.
Step 1: Since 8045 > 561, we apply the division lemma to 8045 and 561, to get
8045 = 561 x 14 + 191
Step 2: Since the reminder 561 ≠ 0, we apply division lemma to 191 and 561, to get
561 = 191 x 2 + 179
Step 3: We consider the new divisor 191 and the new remainder 179, and apply the division lemma to get
191 = 179 x 1 + 12
We consider the new divisor 179 and the new remainder 12,and apply the division lemma to get
179 = 12 x 14 + 11
We consider the new divisor 12 and the new remainder 11,and apply the division lemma to get
12 = 11 x 1 + 1
We consider the new divisor 11 and the new remainder 1,and apply the division lemma to get
11 = 1 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 561 and 8045 is 1
Notice that 1 = HCF(11,1) = HCF(12,11) = HCF(179,12) = HCF(191,179) = HCF(561,191) = HCF(8045,561) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
