HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 617, 4845, 7404 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 617, 4845, 7404 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 617, 4845, 7404 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 617, 4845, 7404 is 1.
HCF(617, 4845, 7404) = 1
HCF of 617, 4845, 7404 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 617, 4845, 7404 is 1.
Highest Common Factor of 617,4845,7404 is 1
Step 1: Since 4845 > 617, we apply the division lemma to 4845 and 617, to get
4845 = 617 x 7 + 526
Step 2: Since the reminder 617 ≠ 0, we apply division lemma to 526 and 617, to get
617 = 526 x 1 + 91
Step 3: We consider the new divisor 526 and the new remainder 91, and apply the division lemma to get
526 = 91 x 5 + 71
We consider the new divisor 91 and the new remainder 71,and apply the division lemma to get
91 = 71 x 1 + 20
We consider the new divisor 71 and the new remainder 20,and apply the division lemma to get
71 = 20 x 3 + 11
We consider the new divisor 20 and the new remainder 11,and apply the division lemma to get
20 = 11 x 1 + 9
We consider the new divisor 11 and the new remainder 9,and apply the division lemma to get
11 = 9 x 1 + 2
We consider the new divisor 9 and the new remainder 2,and apply the division lemma to get
9 = 2 x 4 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 617 and 4845 is 1
Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(11,9) = HCF(20,11) = HCF(71,20) = HCF(91,71) = HCF(526,91) = HCF(617,526) = HCF(4845,617) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 7404 > 1, we apply the division lemma to 7404 and 1, to get
7404 = 1 x 7404 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 7404 is 1
Notice that 1 = HCF(7404,1) .
