HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 385, 265, 340 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 385, 265, 340 is 5 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 385, 265, 340 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 385, 265, 340 is 5.
HCF(385, 265, 340) = 5
HCF of 385, 265, 340 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 385, 265, 340 is 5.
Highest Common Factor of 385,265,340 is 5
Step 1: Since 385 > 265, we apply the division lemma to 385 and 265, to get
385 = 265 x 1 + 120
Step 2: Since the reminder 265 ≠ 0, we apply division lemma to 120 and 265, to get
265 = 120 x 2 + 25
Step 3: We consider the new divisor 120 and the new remainder 25, and apply the division lemma to get
120 = 25 x 4 + 20
We consider the new divisor 25 and the new remainder 20,and apply the division lemma to get
25 = 20 x 1 + 5
We consider the new divisor 20 and the new remainder 5,and apply the division lemma to get
20 = 5 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 385 and 265 is 5
Notice that 5 = HCF(20,5) = HCF(25,20) = HCF(120,25) = HCF(265,120) = HCF(385,265) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 340 > 5, we apply the division lemma to 340 and 5, to get
340 = 5 x 68 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 5 and 340 is 5
Notice that 5 = HCF(340,5) .
