HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 930, 807 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 930, 807 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 930, 807 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 930, 807 is 3.
HCF(930, 807) = 3
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 930, 807 is 3.
Step 1: Since 930 > 807, we apply the division lemma to 930 and 807, to get
930 = 807 x 1 + 123
Step 2: Since the reminder 807 ≠ 0, we apply division lemma to 123 and 807, to get
807 = 123 x 6 + 69
Step 3: We consider the new divisor 123 and the new remainder 69, and apply the division lemma to get
123 = 69 x 1 + 54
We consider the new divisor 69 and the new remainder 54,and apply the division lemma to get
69 = 54 x 1 + 15
We consider the new divisor 54 and the new remainder 15,and apply the division lemma to get
54 = 15 x 3 + 9
We consider the new divisor 15 and the new remainder 9,and apply the division lemma to get
15 = 9 x 1 + 6
We consider the new divisor 9 and the new remainder 6,and apply the division lemma to get
9 = 6 x 1 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 930 and 807 is 3
Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(15,9) = HCF(54,15) = HCF(69,54) = HCF(123,69) = HCF(807,123) = HCF(930,807) .
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 930, 807?
Answer: HCF of 930, 807 is 3 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 930, 807 using Euclid's Algorithm?
Answer: For arbitrary numbers 930, 807 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
