HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 970, 700, 629 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 970, 700, 629 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 970, 700, 629 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 970, 700, 629 is 1.
HCF(970, 700, 629) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 970, 700, 629 is 1.
Step 1: Since 970 > 700, we apply the division lemma to 970 and 700, to get
970 = 700 x 1 + 270
Step 2: Since the reminder 700 ≠ 0, we apply division lemma to 270 and 700, to get
700 = 270 x 2 + 160
Step 3: We consider the new divisor 270 and the new remainder 160, and apply the division lemma to get
270 = 160 x 1 + 110
We consider the new divisor 160 and the new remainder 110,and apply the division lemma to get
160 = 110 x 1 + 50
We consider the new divisor 110 and the new remainder 50,and apply the division lemma to get
110 = 50 x 2 + 10
We consider the new divisor 50 and the new remainder 10,and apply the division lemma to get
50 = 10 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 10, the HCF of 970 and 700 is 10
Notice that 10 = HCF(50,10) = HCF(110,50) = HCF(160,110) = HCF(270,160) = HCF(700,270) = HCF(970,700) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 629 > 10, we apply the division lemma to 629 and 10, to get
629 = 10 x 62 + 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 629 is 1
Notice that 1 = HCF(9,1) = HCF(10,9) = HCF(629,10) .
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 970, 700, 629?
Answer: HCF of 970, 700, 629 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 970, 700, 629 using Euclid's Algorithm?
Answer: For arbitrary numbers 970, 700, 629 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
