HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 770, 703, 425 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 770, 703, 425 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, 703, 425 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, 703, 425 is 1.
HCF(770, 703, 425) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 770, 703, 425 is 1.
Step 1: Since 770 > 703, we apply the division lemma to 770 and 703, to get
770 = 703 x 1 + 67
Step 2: Since the reminder 703 ≠ 0, we apply division lemma to 67 and 703, to get
703 = 67 x 10 + 33
Step 3: We consider the new divisor 67 and the new remainder 33, and apply the division lemma to get
67 = 33 x 2 + 1
We consider the new divisor 33 and the new remainder 1, and apply the division lemma to get
33 = 1 x 33 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 770 and 703 is 1
Notice that 1 = HCF(33,1) = HCF(67,33) = HCF(703,67) = HCF(770,703) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 425 > 1, we apply the division lemma to 425 and 1, to get
425 = 1 x 425 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 425 is 1
Notice that 1 = HCF(425,1) .
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 770, 703, 425?
Answer: HCF of 770, 703, 425 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 770, 703, 425 using Euclid's Algorithm?
Answer: For arbitrary numbers 770, 703, 425 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
