HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 472, 775, 90 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 472, 775, 90 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 472, 775, 90 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 472, 775, 90 is 1.
HCF(472, 775, 90) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 472, 775, 90 is 1.
Step 1: Since 775 > 472, we apply the division lemma to 775 and 472, to get
775 = 472 x 1 + 303
Step 2: Since the reminder 472 ≠ 0, we apply division lemma to 303 and 472, to get
472 = 303 x 1 + 169
Step 3: We consider the new divisor 303 and the new remainder 169, and apply the division lemma to get
303 = 169 x 1 + 134
We consider the new divisor 169 and the new remainder 134,and apply the division lemma to get
169 = 134 x 1 + 35
We consider the new divisor 134 and the new remainder 35,and apply the division lemma to get
134 = 35 x 3 + 29
We consider the new divisor 35 and the new remainder 29,and apply the division lemma to get
35 = 29 x 1 + 6
We consider the new divisor 29 and the new remainder 6,and apply the division lemma to get
29 = 6 x 4 + 5
We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get
6 = 5 x 1 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 472 and 775 is 1
Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(29,6) = HCF(35,29) = HCF(134,35) = HCF(169,134) = HCF(303,169) = HCF(472,303) = HCF(775,472) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 90 > 1, we apply the division lemma to 90 and 1, to get
90 = 1 x 90 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 90 is 1
Notice that 1 = HCF(90,1) .
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 472, 775, 90?
Answer: HCF of 472, 775, 90 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 472, 775, 90 using Euclid's Algorithm?
Answer: For arbitrary numbers 472, 775, 90 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
