HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 742, 7637, 8795 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 742, 7637, 8795 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 742, 7637, 8795 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 742, 7637, 8795 is 1.
HCF(742, 7637, 8795) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 742, 7637, 8795 is 1.
Step 1: Since 7637 > 742, we apply the division lemma to 7637 and 742, to get
7637 = 742 x 10 + 217
Step 2: Since the reminder 742 ≠ 0, we apply division lemma to 217 and 742, to get
742 = 217 x 3 + 91
Step 3: We consider the new divisor 217 and the new remainder 91, and apply the division lemma to get
217 = 91 x 2 + 35
We consider the new divisor 91 and the new remainder 35,and apply the division lemma to get
91 = 35 x 2 + 21
We consider the new divisor 35 and the new remainder 21,and apply the division lemma to get
35 = 21 x 1 + 14
We consider the new divisor 21 and the new remainder 14,and apply the division lemma to get
21 = 14 x 1 + 7
We consider the new divisor 14 and the new remainder 7,and apply the division lemma to get
14 = 7 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 742 and 7637 is 7
Notice that 7 = HCF(14,7) = HCF(21,14) = HCF(35,21) = HCF(91,35) = HCF(217,91) = HCF(742,217) = HCF(7637,742) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 8795 > 7, we apply the division lemma to 8795 and 7, to get
8795 = 7 x 1256 + 3
Step 2: Since the reminder 7 ≠ 0, we apply division lemma to 3 and 7, to get
7 = 3 x 2 + 1
Step 3: We consider the new divisor 3 and the new remainder 1, and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 7 and 8795 is 1
Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(8795,7) .
Here are some samples of HCF using Euclid's Algorithm calculations.
