HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 641, 748 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 641, 748 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 641, 748 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 641, 748 is 1.
HCF(641, 748) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 641, 748 is 1.
Step 1: Since 748 > 641, we apply the division lemma to 748 and 641, to get
748 = 641 x 1 + 107
Step 2: Since the reminder 641 ≠ 0, we apply division lemma to 107 and 641, to get
641 = 107 x 5 + 106
Step 3: We consider the new divisor 107 and the new remainder 106, and apply the division lemma to get
107 = 106 x 1 + 1
We consider the new divisor 106 and the new remainder 1, and apply the division lemma to get
106 = 1 x 106 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 641 and 748 is 1
Notice that 1 = HCF(106,1) = HCF(107,106) = HCF(641,107) = HCF(748,641) .
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 641, 748?
Answer: HCF of 641, 748 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 641, 748 using Euclid's Algorithm?
Answer: For arbitrary numbers 641, 748 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
