HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 290, 783, 75 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 290, 783, 75 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 290, 783, 75 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 290, 783, 75 is 1.
HCF(290, 783, 75) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 290, 783, 75 is 1.
Step 1: Since 783 > 290, we apply the division lemma to 783 and 290, to get
783 = 290 x 2 + 203
Step 2: Since the reminder 290 ≠ 0, we apply division lemma to 203 and 290, to get
290 = 203 x 1 + 87
Step 3: We consider the new divisor 203 and the new remainder 87, and apply the division lemma to get
203 = 87 x 2 + 29
We consider the new divisor 87 and the new remainder 29, and apply the division lemma to get
87 = 29 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 29, the HCF of 290 and 783 is 29
Notice that 29 = HCF(87,29) = HCF(203,87) = HCF(290,203) = HCF(783,290) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 75 > 29, we apply the division lemma to 75 and 29, to get
75 = 29 x 2 + 17
Step 2: Since the reminder 29 ≠ 0, we apply division lemma to 17 and 29, to get
29 = 17 x 1 + 12
Step 3: We consider the new divisor 17 and the new remainder 12, and apply the division lemma to get
17 = 12 x 1 + 5
We consider the new divisor 12 and the new remainder 5,and apply the division lemma to get
12 = 5 x 2 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 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 29 and 75 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(12,5) = HCF(17,12) = HCF(29,17) = HCF(75,29) .
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 290, 783, 75?
Answer: HCF of 290, 783, 75 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 290, 783, 75 using Euclid's Algorithm?
