HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 686, 240, 46 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 686, 240, 46 is 2 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 686, 240, 46 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 686, 240, 46 is 2.
HCF(686, 240, 46) = 2
HCF of 686, 240, 46 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 686, 240, 46 is 2.
Highest Common Factor of 686,240,46 is 2
Step 1: Since 686 > 240, we apply the division lemma to 686 and 240, to get
686 = 240 x 2 + 206
Step 2: Since the reminder 240 ≠ 0, we apply division lemma to 206 and 240, to get
240 = 206 x 1 + 34
Step 3: We consider the new divisor 206 and the new remainder 34, and apply the division lemma to get
206 = 34 x 6 + 2
We consider the new divisor 34 and the new remainder 2, and apply the division lemma to get
34 = 2 x 17 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 686 and 240 is 2
Notice that 2 = HCF(34,2) = HCF(206,34) = HCF(240,206) = HCF(686,240) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 46 > 2, we apply the division lemma to 46 and 2, to get
46 = 2 x 23 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 46 is 2
Notice that 2 = HCF(46,2) .
