HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 374, 631, 87 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 374, 631, 87 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 374, 631, 87 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 374, 631, 87 is 1.
HCF(374, 631, 87) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 374, 631, 87 is 1.
Step 1: Since 631 > 374, we apply the division lemma to 631 and 374, to get
631 = 374 x 1 + 257
Step 2: Since the reminder 374 ≠ 0, we apply division lemma to 257 and 374, to get
374 = 257 x 1 + 117
Step 3: We consider the new divisor 257 and the new remainder 117, and apply the division lemma to get
257 = 117 x 2 + 23
We consider the new divisor 117 and the new remainder 23,and apply the division lemma to get
117 = 23 x 5 + 2
We consider the new divisor 23 and the new remainder 2,and apply the division lemma to get
23 = 2 x 11 + 1
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 374 and 631 is 1
Notice that 1 = HCF(2,1) = HCF(23,2) = HCF(117,23) = HCF(257,117) = HCF(374,257) = HCF(631,374) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 87 > 1, we apply the division lemma to 87 and 1, to get
87 = 1 x 87 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 87 is 1
Notice that 1 = HCF(87,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 374, 631, 87?
Answer: HCF of 374, 631, 87 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 374, 631, 87 using Euclid's Algorithm?
Answer: For arbitrary numbers 374, 631, 87 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
