HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 639, 758 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 639, 758 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 639, 758 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 639, 758 is 1.
HCF(639, 758) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 639, 758 is 1.
Step 1: Since 758 > 639, we apply the division lemma to 758 and 639, to get
758 = 639 x 1 + 119
Step 2: Since the reminder 639 ≠ 0, we apply division lemma to 119 and 639, to get
639 = 119 x 5 + 44
Step 3: We consider the new divisor 119 and the new remainder 44, and apply the division lemma to get
119 = 44 x 2 + 31
We consider the new divisor 44 and the new remainder 31,and apply the division lemma to get
44 = 31 x 1 + 13
We consider the new divisor 31 and the new remainder 13,and apply the division lemma to get
31 = 13 x 2 + 5
We consider the new divisor 13 and the new remainder 5,and apply the division lemma to get
13 = 5 x 2 + 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 639 and 758 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(13,5) = HCF(31,13) = HCF(44,31) = HCF(119,44) = HCF(639,119) = HCF(758,639) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 639, 758?
Answer: HCF of 639, 758 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 639, 758 using Euclid's Algorithm?
Answer: For arbitrary numbers 639, 758 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
