HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 995, 438 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 995, 438 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, 438 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, 438 is 1.
HCF(995, 438) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 995, 438 is 1.
Step 1: Since 995 > 438, we apply the division lemma to 995 and 438, to get
995 = 438 x 2 + 119
Step 2: Since the reminder 438 ≠ 0, we apply division lemma to 119 and 438, to get
438 = 119 x 3 + 81
Step 3: We consider the new divisor 119 and the new remainder 81, and apply the division lemma to get
119 = 81 x 1 + 38
We consider the new divisor 81 and the new remainder 38,and apply the division lemma to get
81 = 38 x 2 + 5
We consider the new divisor 38 and the new remainder 5,and apply the division lemma to get
38 = 5 x 7 + 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 995 and 438 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(38,5) = HCF(81,38) = HCF(119,81) = HCF(438,119) = HCF(995,438) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
Answer: Euclid's Division Algorithm is a technique to compute the Highest Common Factor (HCF) of given positive integers.
2. what is the HCF of 995, 438?
Answer: HCF of 995, 438 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 995, 438 using Euclid's Algorithm?
Answer: For arbitrary numbers 995, 438 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
