HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 680, 540, 692 i.e. 4 the largest integer that leaves a remainder zero for all numbers.
HCF of 680, 540, 692 is 4 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 680, 540, 692 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 680, 540, 692 is 4.
HCF(680, 540, 692) = 4
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 680, 540, 692 is 4.
Step 1: Since 680 > 540, we apply the division lemma to 680 and 540, to get
680 = 540 x 1 + 140
Step 2: Since the reminder 540 ≠ 0, we apply division lemma to 140 and 540, to get
540 = 140 x 3 + 120
Step 3: We consider the new divisor 140 and the new remainder 120, and apply the division lemma to get
140 = 120 x 1 + 20
We consider the new divisor 120 and the new remainder 20, and apply the division lemma to get
120 = 20 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 20, the HCF of 680 and 540 is 20
Notice that 20 = HCF(120,20) = HCF(140,120) = HCF(540,140) = HCF(680,540) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 692 > 20, we apply the division lemma to 692 and 20, to get
692 = 20 x 34 + 12
Step 2: Since the reminder 20 ≠ 0, we apply division lemma to 12 and 20, to get
20 = 12 x 1 + 8
Step 3: We consider the new divisor 12 and the new remainder 8, and apply the division lemma to get
12 = 8 x 1 + 4
We consider the new divisor 8 and the new remainder 4, and apply the division lemma to get
8 = 4 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 20 and 692 is 4
Notice that 4 = HCF(8,4) = HCF(12,8) = HCF(20,12) = HCF(692,20) .
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 680, 540, 692?
Answer: HCF of 680, 540, 692 is 4 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 680, 540, 692 using Euclid's Algorithm?
Answer: For arbitrary numbers 680, 540, 692 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
