HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 8638, 1939 i.e. 7 the largest integer that leaves a remainder zero for all numbers.
HCF of 8638, 1939 is 7 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 8638, 1939 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 8638, 1939 is 7.
HCF(8638, 1939) = 7
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 8638, 1939 is 7.
Step 1: Since 8638 > 1939, we apply the division lemma to 8638 and 1939, to get
8638 = 1939 x 4 + 882
Step 2: Since the reminder 1939 ≠ 0, we apply division lemma to 882 and 1939, to get
1939 = 882 x 2 + 175
Step 3: We consider the new divisor 882 and the new remainder 175, and apply the division lemma to get
882 = 175 x 5 + 7
We consider the new divisor 175 and the new remainder 7, and apply the division lemma to get
175 = 7 x 25 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 8638 and 1939 is 7
Notice that 7 = HCF(175,7) = HCF(882,175) = HCF(1939,882) = HCF(8638,1939) .
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 8638, 1939?
Answer: HCF of 8638, 1939 is 7 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 8638, 1939 using Euclid's Algorithm?
Answer: For arbitrary numbers 8638, 1939 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
