HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 632, 7939, 4639 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 632, 7939, 4639 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 632, 7939, 4639 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 632, 7939, 4639 is 1.
HCF(632, 7939, 4639) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 632, 7939, 4639 is 1.
Step 1: Since 7939 > 632, we apply the division lemma to 7939 and 632, to get
7939 = 632 x 12 + 355
Step 2: Since the reminder 632 ≠ 0, we apply division lemma to 355 and 632, to get
632 = 355 x 1 + 277
Step 3: We consider the new divisor 355 and the new remainder 277, and apply the division lemma to get
355 = 277 x 1 + 78
We consider the new divisor 277 and the new remainder 78,and apply the division lemma to get
277 = 78 x 3 + 43
We consider the new divisor 78 and the new remainder 43,and apply the division lemma to get
78 = 43 x 1 + 35
We consider the new divisor 43 and the new remainder 35,and apply the division lemma to get
43 = 35 x 1 + 8
We consider the new divisor 35 and the new remainder 8,and apply the division lemma to get
35 = 8 x 4 + 3
We consider the new divisor 8 and the new remainder 3,and apply the division lemma to get
8 = 3 x 2 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 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 632 and 7939 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(8,3) = HCF(35,8) = HCF(43,35) = HCF(78,43) = HCF(277,78) = HCF(355,277) = HCF(632,355) = HCF(7939,632) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 4639 > 1, we apply the division lemma to 4639 and 1, to get
4639 = 1 x 4639 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 4639 is 1
Notice that 1 = HCF(4639,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
