HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 438, 677 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 438, 677 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 438, 677 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 438, 677 is 1.
HCF(438, 677) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 438, 677 is 1.
Step 1: Since 677 > 438, we apply the division lemma to 677 and 438, to get
677 = 438 x 1 + 239
Step 2: Since the reminder 438 ≠ 0, we apply division lemma to 239 and 438, to get
438 = 239 x 1 + 199
Step 3: We consider the new divisor 239 and the new remainder 199, and apply the division lemma to get
239 = 199 x 1 + 40
We consider the new divisor 199 and the new remainder 40,and apply the division lemma to get
199 = 40 x 4 + 39
We consider the new divisor 40 and the new remainder 39,and apply the division lemma to get
40 = 39 x 1 + 1
We consider the new divisor 39 and the new remainder 1,and apply the division lemma to get
39 = 1 x 39 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 438 and 677 is 1
Notice that 1 = HCF(39,1) = HCF(40,39) = HCF(199,40) = HCF(239,199) = HCF(438,239) = HCF(677,438) .
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 438, 677?
Answer: HCF of 438, 677 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 438, 677 using Euclid's Algorithm?
Answer: For arbitrary numbers 438, 677 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
