HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 820, 575, 359 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 820, 575, 359 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 820, 575, 359 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 820, 575, 359 is 1.
HCF(820, 575, 359) = 1
HCF of 820, 575, 359 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 820, 575, 359 is 1.
Highest Common Factor of 820,575,359 is 1
Step 1: Since 820 > 575, we apply the division lemma to 820 and 575, to get
820 = 575 x 1 + 245
Step 2: Since the reminder 575 ≠ 0, we apply division lemma to 245 and 575, to get
575 = 245 x 2 + 85
Step 3: We consider the new divisor 245 and the new remainder 85, and apply the division lemma to get
245 = 85 x 2 + 75
We consider the new divisor 85 and the new remainder 75,and apply the division lemma to get
85 = 75 x 1 + 10
We consider the new divisor 75 and the new remainder 10,and apply the division lemma to get
75 = 10 x 7 + 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 820 and 575 is 5
Notice that 5 = HCF(10,5) = HCF(75,10) = HCF(85,75) = HCF(245,85) = HCF(575,245) = HCF(820,575) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 359 > 5, we apply the division lemma to 359 and 5, to get
359 = 5 x 71 + 4
Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 4 and 5, to get
5 = 4 x 1 + 1
Step 3: We consider the new divisor 4 and the new remainder 1, and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 5 and 359 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(359,5) .
