HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 752, 959, 313 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 752, 959, 313 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 752, 959, 313 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 752, 959, 313 is 1.
HCF(752, 959, 313) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 752, 959, 313 is 1.
Step 1: Since 959 > 752, we apply the division lemma to 959 and 752, to get
959 = 752 x 1 + 207
Step 2: Since the reminder 752 ≠ 0, we apply division lemma to 207 and 752, to get
752 = 207 x 3 + 131
Step 3: We consider the new divisor 207 and the new remainder 131, and apply the division lemma to get
207 = 131 x 1 + 76
We consider the new divisor 131 and the new remainder 76,and apply the division lemma to get
131 = 76 x 1 + 55
We consider the new divisor 76 and the new remainder 55,and apply the division lemma to get
76 = 55 x 1 + 21
We consider the new divisor 55 and the new remainder 21,and apply the division lemma to get
55 = 21 x 2 + 13
We consider the new divisor 21 and the new remainder 13,and apply the division lemma to get
21 = 13 x 1 + 8
We consider the new divisor 13 and the new remainder 8,and apply the division lemma to get
13 = 8 x 1 + 5
We consider the new divisor 8 and the new remainder 5,and apply the division lemma to get
8 = 5 x 1 + 3
We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get
5 = 3 x 1 + 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 752 and 959 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(13,8) = HCF(21,13) = HCF(55,21) = HCF(76,55) = HCF(131,76) = HCF(207,131) = HCF(752,207) = HCF(959,752) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 313 > 1, we apply the division lemma to 313 and 1, to get
313 = 1 x 313 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 313 is 1
Notice that 1 = HCF(313,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
