HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 269, 230, 855 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 269, 230, 855 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 269, 230, 855 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 269, 230, 855 is 1.
HCF(269, 230, 855) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 269, 230, 855 is 1.
Step 1: Since 269 > 230, we apply the division lemma to 269 and 230, to get
269 = 230 x 1 + 39
Step 2: Since the reminder 230 ≠ 0, we apply division lemma to 39 and 230, to get
230 = 39 x 5 + 35
Step 3: We consider the new divisor 39 and the new remainder 35, and apply the division lemma to get
39 = 35 x 1 + 4
We consider the new divisor 35 and the new remainder 4,and apply the division lemma to get
35 = 4 x 8 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 269 and 230 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(35,4) = HCF(39,35) = HCF(230,39) = HCF(269,230) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 855 > 1, we apply the division lemma to 855 and 1, to get
855 = 1 x 855 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 855 is 1
Notice that 1 = HCF(855,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
