HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 924, 261, 315 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 924, 261, 315 is 3 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 924, 261, 315 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 924, 261, 315 is 3.
HCF(924, 261, 315) = 3
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 924, 261, 315 is 3.
Step 1: Since 924 > 261, we apply the division lemma to 924 and 261, to get
924 = 261 x 3 + 141
Step 2: Since the reminder 261 ≠ 0, we apply division lemma to 141 and 261, to get
261 = 141 x 1 + 120
Step 3: We consider the new divisor 141 and the new remainder 120, and apply the division lemma to get
141 = 120 x 1 + 21
We consider the new divisor 120 and the new remainder 21,and apply the division lemma to get
120 = 21 x 5 + 15
We consider the new divisor 21 and the new remainder 15,and apply the division lemma to get
21 = 15 x 1 + 6
We consider the new divisor 15 and the new remainder 6,and apply the division lemma to get
15 = 6 x 2 + 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 924 and 261 is 3
Notice that 3 = HCF(6,3) = HCF(15,6) = HCF(21,15) = HCF(120,21) = HCF(141,120) = HCF(261,141) = HCF(924,261) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 315 > 3, we apply the division lemma to 315 and 3, to get
315 = 3 x 105 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 315 is 3
Notice that 3 = HCF(315,3) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 924, 261, 315?
Answer: HCF of 924, 261, 315 is 3 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 924, 261, 315 using Euclid's Algorithm?
Answer: For arbitrary numbers 924, 261, 315 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
