HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 680, 480, 617 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 680, 480, 617 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 680, 480, 617 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, 480, 617 is 1.
HCF(680, 480, 617) = 1
HCF of 680, 480, 617 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 680, 480, 617 is 1.
Highest Common Factor of 680,480,617 is 1
Step 1: Since 680 > 480, we apply the division lemma to 680 and 480, to get
680 = 480 x 1 + 200
Step 2: Since the reminder 480 ≠ 0, we apply division lemma to 200 and 480, to get
480 = 200 x 2 + 80
Step 3: We consider the new divisor 200 and the new remainder 80, and apply the division lemma to get
200 = 80 x 2 + 40
We consider the new divisor 80 and the new remainder 40, and apply the division lemma to get
80 = 40 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 40, the HCF of 680 and 480 is 40
Notice that 40 = HCF(80,40) = HCF(200,80) = HCF(480,200) = HCF(680,480) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 617 > 40, we apply the division lemma to 617 and 40, to get
617 = 40 x 15 + 17
Step 2: Since the reminder 40 ≠ 0, we apply division lemma to 17 and 40, to get
40 = 17 x 2 + 6
Step 3: We consider the new divisor 17 and the new remainder 6, and apply the division lemma to get
17 = 6 x 2 + 5
We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get
6 = 5 x 1 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 40 and 617 is 1
Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(17,6) = HCF(40,17) = HCF(617,40) .
