HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 758, 439 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 758, 439 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 758, 439 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 758, 439 is 1.
HCF(758, 439) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 758, 439 is 1.
Step 1: Since 758 > 439, we apply the division lemma to 758 and 439, to get
758 = 439 x 1 + 319
Step 2: Since the reminder 439 ≠ 0, we apply division lemma to 319 and 439, to get
439 = 319 x 1 + 120
Step 3: We consider the new divisor 319 and the new remainder 120, and apply the division lemma to get
319 = 120 x 2 + 79
We consider the new divisor 120 and the new remainder 79,and apply the division lemma to get
120 = 79 x 1 + 41
We consider the new divisor 79 and the new remainder 41,and apply the division lemma to get
79 = 41 x 1 + 38
We consider the new divisor 41 and the new remainder 38,and apply the division lemma to get
41 = 38 x 1 + 3
We consider the new divisor 38 and the new remainder 3,and apply the division lemma to get
38 = 3 x 12 + 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 758 and 439 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(38,3) = HCF(41,38) = HCF(79,41) = HCF(120,79) = HCF(319,120) = HCF(439,319) = HCF(758,439) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 758, 439?
Answer: HCF of 758, 439 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 758, 439 using Euclid's Algorithm?
Answer: For arbitrary numbers 758, 439 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
