HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 758, 445 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 758, 445 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, 445 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, 445 is 1.
HCF(758, 445) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 758, 445 is 1.
Step 1: Since 758 > 445, we apply the division lemma to 758 and 445, to get
758 = 445 x 1 + 313
Step 2: Since the reminder 445 ≠ 0, we apply division lemma to 313 and 445, to get
445 = 313 x 1 + 132
Step 3: We consider the new divisor 313 and the new remainder 132, and apply the division lemma to get
313 = 132 x 2 + 49
We consider the new divisor 132 and the new remainder 49,and apply the division lemma to get
132 = 49 x 2 + 34
We consider the new divisor 49 and the new remainder 34,and apply the division lemma to get
49 = 34 x 1 + 15
We consider the new divisor 34 and the new remainder 15,and apply the division lemma to get
34 = 15 x 2 + 4
We consider the new divisor 15 and the new remainder 4,and apply the division lemma to get
15 = 4 x 3 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 758 and 445 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(15,4) = HCF(34,15) = HCF(49,34) = HCF(132,49) = HCF(313,132) = HCF(445,313) = HCF(758,445) .
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, 445?
Answer: HCF of 758, 445 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 758, 445 using Euclid's Algorithm?
Answer: For arbitrary numbers 758, 445 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
