HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 672, 714, 603 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 672, 714, 603 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 672, 714, 603 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 672, 714, 603 is 3.
HCF(672, 714, 603) = 3
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 672, 714, 603 is 3.
Step 1: Since 714 > 672, we apply the division lemma to 714 and 672, to get
714 = 672 x 1 + 42
Step 2: Since the reminder 672 ≠ 0, we apply division lemma to 42 and 672, to get
672 = 42 x 16 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 42, the HCF of 672 and 714 is 42
Notice that 42 = HCF(672,42) = HCF(714,672) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 603 > 42, we apply the division lemma to 603 and 42, to get
603 = 42 x 14 + 15
Step 2: Since the reminder 42 ≠ 0, we apply division lemma to 15 and 42, to get
42 = 15 x 2 + 12
Step 3: We consider the new divisor 15 and the new remainder 12, and apply the division lemma to get
15 = 12 x 1 + 3
We consider the new divisor 12 and the new remainder 3, and apply the division lemma to get
12 = 3 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 42 and 603 is 3
Notice that 3 = HCF(12,3) = HCF(15,12) = HCF(42,15) = HCF(603,42) .
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 672, 714, 603?
Answer: HCF of 672, 714, 603 is 3 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 672, 714, 603 using Euclid's Algorithm?
Answer: For arbitrary numbers 672, 714, 603 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
