HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 255, 5575, 4520 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 255, 5575, 4520 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 255, 5575, 4520 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 255, 5575, 4520 is 5.
HCF(255, 5575, 4520) = 5
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 255, 5575, 4520 is 5.
Step 1: Since 5575 > 255, we apply the division lemma to 5575 and 255, to get
5575 = 255 x 21 + 220
Step 2: Since the reminder 255 ≠ 0, we apply division lemma to 220 and 255, to get
255 = 220 x 1 + 35
Step 3: We consider the new divisor 220 and the new remainder 35, and apply the division lemma to get
220 = 35 x 6 + 10
We consider the new divisor 35 and the new remainder 10,and apply the division lemma to get
35 = 10 x 3 + 5
We consider the new divisor 10 and the new remainder 5,and apply the division lemma to get
10 = 5 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 255 and 5575 is 5
Notice that 5 = HCF(10,5) = HCF(35,10) = HCF(220,35) = HCF(255,220) = HCF(5575,255) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 4520 > 5, we apply the division lemma to 4520 and 5, to get
4520 = 5 x 904 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 5 and 4520 is 5
Notice that 5 = HCF(4520,5) .
Here are some samples of HCF using Euclid's Algorithm calculations.
