HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 316, 569, 117, 661 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 316, 569, 117, 661 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 316, 569, 117, 661 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 316, 569, 117, 661 is 1.
HCF(316, 569, 117, 661) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 316, 569, 117, 661 is 1.
Step 1: Since 569 > 316, we apply the division lemma to 569 and 316, to get
569 = 316 x 1 + 253
Step 2: Since the reminder 316 ≠ 0, we apply division lemma to 253 and 316, to get
316 = 253 x 1 + 63
Step 3: We consider the new divisor 253 and the new remainder 63, and apply the division lemma to get
253 = 63 x 4 + 1
We consider the new divisor 63 and the new remainder 1, and apply the division lemma to get
63 = 1 x 63 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 316 and 569 is 1
Notice that 1 = HCF(63,1) = HCF(253,63) = HCF(316,253) = HCF(569,316) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 117 > 1, we apply the division lemma to 117 and 1, to get
117 = 1 x 117 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 117 is 1
Notice that 1 = HCF(117,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 661 > 1, we apply the division lemma to 661 and 1, to get
661 = 1 x 661 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 661 is 1
Notice that 1 = HCF(661,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 316, 569, 117, 661?
Answer: HCF of 316, 569, 117, 661 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 316, 569, 117, 661 using Euclid's Algorithm?
Answer: For arbitrary numbers 316, 569, 117, 661 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
