HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 770, 510, 919 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 770, 510, 919 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 770, 510, 919 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 770, 510, 919 is 1.
HCF(770, 510, 919) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 770, 510, 919 is 1.
Step 1: Since 770 > 510, we apply the division lemma to 770 and 510, to get
770 = 510 x 1 + 260
Step 2: Since the reminder 510 ≠ 0, we apply division lemma to 260 and 510, to get
510 = 260 x 1 + 250
Step 3: We consider the new divisor 260 and the new remainder 250, and apply the division lemma to get
260 = 250 x 1 + 10
We consider the new divisor 250 and the new remainder 10, and apply the division lemma to get
250 = 10 x 25 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 10, the HCF of 770 and 510 is 10
Notice that 10 = HCF(250,10) = HCF(260,250) = HCF(510,260) = HCF(770,510) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 919 > 10, we apply the division lemma to 919 and 10, to get
919 = 10 x 91 + 9
Step 2: Since the reminder 10 ≠ 0, we apply division lemma to 9 and 10, to get
10 = 9 x 1 + 1
Step 3: We consider the new divisor 9 and the new remainder 1, and apply the division lemma to get
9 = 1 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 10 and 919 is 1
Notice that 1 = HCF(9,1) = HCF(10,9) = HCF(919,10) .
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 770, 510, 919?
Answer: HCF of 770, 510, 919 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 770, 510, 919 using Euclid's Algorithm?
Answer: For arbitrary numbers 770, 510, 919 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
