HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 88, 18, 87, 503 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 88, 18, 87, 503 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 88, 18, 87, 503 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 88, 18, 87, 503 is 1.
HCF(88, 18, 87, 503) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 88, 18, 87, 503 is 1.
Step 1: Since 88 > 18, we apply the division lemma to 88 and 18, to get
88 = 18 x 4 + 16
Step 2: Since the reminder 18 ≠ 0, we apply division lemma to 16 and 18, to get
18 = 16 x 1 + 2
Step 3: We consider the new divisor 16 and the new remainder 2, and apply the division lemma to get
16 = 2 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 88 and 18 is 2
Notice that 2 = HCF(16,2) = HCF(18,16) = HCF(88,18) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 87 > 2, we apply the division lemma to 87 and 2, to get
87 = 2 x 43 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 87 is 1
Notice that 1 = HCF(2,1) = HCF(87,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 503 > 1, we apply the division lemma to 503 and 1, to get
503 = 1 x 503 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 503 is 1
Notice that 1 = HCF(503,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 88, 18, 87, 503?
Answer: HCF of 88, 18, 87, 503 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 88, 18, 87, 503 using Euclid's Algorithm?
Answer: For arbitrary numbers 88, 18, 87, 503 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
