HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 525, 801, 379 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 525, 801, 379 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 525, 801, 379 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 525, 801, 379 is 1.
HCF(525, 801, 379) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 525, 801, 379 is 1.
Step 1: Since 801 > 525, we apply the division lemma to 801 and 525, to get
801 = 525 x 1 + 276
Step 2: Since the reminder 525 ≠ 0, we apply division lemma to 276 and 525, to get
525 = 276 x 1 + 249
Step 3: We consider the new divisor 276 and the new remainder 249, and apply the division lemma to get
276 = 249 x 1 + 27
We consider the new divisor 249 and the new remainder 27,and apply the division lemma to get
249 = 27 x 9 + 6
We consider the new divisor 27 and the new remainder 6,and apply the division lemma to get
27 = 6 x 4 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 525 and 801 is 3
Notice that 3 = HCF(6,3) = HCF(27,6) = HCF(249,27) = HCF(276,249) = HCF(525,276) = HCF(801,525) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 379 > 3, we apply the division lemma to 379 and 3, to get
379 = 3 x 126 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, 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 3 and 379 is 1
Notice that 1 = HCF(3,1) = HCF(379,3) .
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 525, 801, 379?
Answer: HCF of 525, 801, 379 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 525, 801, 379 using Euclid's Algorithm?
Answer: For arbitrary numbers 525, 801, 379 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
