HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 995, 821, 953 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 995, 821, 953 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 995, 821, 953 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 995, 821, 953 is 1.
HCF(995, 821, 953) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 995, 821, 953 is 1.
Step 1: Since 995 > 821, we apply the division lemma to 995 and 821, to get
995 = 821 x 1 + 174
Step 2: Since the reminder 821 ≠ 0, we apply division lemma to 174 and 821, to get
821 = 174 x 4 + 125
Step 3: We consider the new divisor 174 and the new remainder 125, and apply the division lemma to get
174 = 125 x 1 + 49
We consider the new divisor 125 and the new remainder 49,and apply the division lemma to get
125 = 49 x 2 + 27
We consider the new divisor 49 and the new remainder 27,and apply the division lemma to get
49 = 27 x 1 + 22
We consider the new divisor 27 and the new remainder 22,and apply the division lemma to get
27 = 22 x 1 + 5
We consider the new divisor 22 and the new remainder 5,and apply the division lemma to get
22 = 5 x 4 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 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 995 and 821 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(22,5) = HCF(27,22) = HCF(49,27) = HCF(125,49) = HCF(174,125) = HCF(821,174) = HCF(995,821) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 953 > 1, we apply the division lemma to 953 and 1, to get
953 = 1 x 953 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 953 is 1
Notice that 1 = HCF(953,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
