HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 915, 501, 106 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 915, 501, 106 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 915, 501, 106 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 915, 501, 106 is 1.
HCF(915, 501, 106) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 915, 501, 106 is 1.
Step 1: Since 915 > 501, we apply the division lemma to 915 and 501, to get
915 = 501 x 1 + 414
Step 2: Since the reminder 501 ≠ 0, we apply division lemma to 414 and 501, to get
501 = 414 x 1 + 87
Step 3: We consider the new divisor 414 and the new remainder 87, and apply the division lemma to get
414 = 87 x 4 + 66
We consider the new divisor 87 and the new remainder 66,and apply the division lemma to get
87 = 66 x 1 + 21
We consider the new divisor 66 and the new remainder 21,and apply the division lemma to get
66 = 21 x 3 + 3
We consider the new divisor 21 and the new remainder 3,and apply the division lemma to get
21 = 3 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 915 and 501 is 3
Notice that 3 = HCF(21,3) = HCF(66,21) = HCF(87,66) = HCF(414,87) = HCF(501,414) = HCF(915,501) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 106 > 3, we apply the division lemma to 106 and 3, to get
106 = 3 x 35 + 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 106 is 1
Notice that 1 = HCF(3,1) = HCF(106,3) .
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 915, 501, 106?
Answer: HCF of 915, 501, 106 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 915, 501, 106 using Euclid's Algorithm?
Answer: For arbitrary numbers 915, 501, 106 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
