HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 745, 300, 762, 13 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 745, 300, 762, 13 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 745, 300, 762, 13 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 745, 300, 762, 13 is 1.
HCF(745, 300, 762, 13) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 745, 300, 762, 13 is 1.
Step 1: Since 745 > 300, we apply the division lemma to 745 and 300, to get
745 = 300 x 2 + 145
Step 2: Since the reminder 300 ≠ 0, we apply division lemma to 145 and 300, to get
300 = 145 x 2 + 10
Step 3: We consider the new divisor 145 and the new remainder 10, and apply the division lemma to get
145 = 10 x 14 + 5
We consider the new divisor 10 and the new remainder 5, and apply the division lemma to get
10 = 5 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 745 and 300 is 5
Notice that 5 = HCF(10,5) = HCF(145,10) = HCF(300,145) = HCF(745,300) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 762 > 5, we apply the division lemma to 762 and 5, to get
762 = 5 x 152 + 2
Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 2 and 5, to get
5 = 2 x 2 + 1
Step 3: 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 5 and 762 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(762,5) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 13 > 1, we apply the division lemma to 13 and 1, to get
13 = 1 x 13 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 13 is 1
Notice that 1 = HCF(13,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 745, 300, 762, 13?
Answer: HCF of 745, 300, 762, 13 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 745, 300, 762, 13 using Euclid's Algorithm?
