HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 5643, 7581, 58022 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 5643, 7581, 58022 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 5643, 7581, 58022 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 5643, 7581, 58022 is 1.
HCF(5643, 7581, 58022) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 5643, 7581, 58022 is 1.
Step 1: Since 7581 > 5643, we apply the division lemma to 7581 and 5643, to get
7581 = 5643 x 1 + 1938
Step 2: Since the reminder 5643 ≠ 0, we apply division lemma to 1938 and 5643, to get
5643 = 1938 x 2 + 1767
Step 3: We consider the new divisor 1938 and the new remainder 1767, and apply the division lemma to get
1938 = 1767 x 1 + 171
We consider the new divisor 1767 and the new remainder 171,and apply the division lemma to get
1767 = 171 x 10 + 57
We consider the new divisor 171 and the new remainder 57,and apply the division lemma to get
171 = 57 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 57, the HCF of 5643 and 7581 is 57
Notice that 57 = HCF(171,57) = HCF(1767,171) = HCF(1938,1767) = HCF(5643,1938) = HCF(7581,5643) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 58022 > 57, we apply the division lemma to 58022 and 57, to get
58022 = 57 x 1017 + 53
Step 2: Since the reminder 57 ≠ 0, we apply division lemma to 53 and 57, to get
57 = 53 x 1 + 4
Step 3: We consider the new divisor 53 and the new remainder 4, and apply the division lemma to get
53 = 4 x 13 + 1
We consider the new divisor 4 and the new remainder 1, and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 57 and 58022 is 1
Notice that 1 = HCF(4,1) = HCF(53,4) = HCF(57,53) = HCF(58022,57) .
Here are some samples of HCF using Euclid's Algorithm calculations.
