HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 545, 317, 860 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 545, 317, 860 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 545, 317, 860 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 545, 317, 860 is 1.
HCF(545, 317, 860) = 1
HCF of 545, 317, 860 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 545, 317, 860 is 1.
Highest Common Factor of 545,317,860 is 1
Step 1: Since 545 > 317, we apply the division lemma to 545 and 317, to get
545 = 317 x 1 + 228
Step 2: Since the reminder 317 ≠ 0, we apply division lemma to 228 and 317, to get
317 = 228 x 1 + 89
Step 3: We consider the new divisor 228 and the new remainder 89, and apply the division lemma to get
228 = 89 x 2 + 50
We consider the new divisor 89 and the new remainder 50,and apply the division lemma to get
89 = 50 x 1 + 39
We consider the new divisor 50 and the new remainder 39,and apply the division lemma to get
50 = 39 x 1 + 11
We consider the new divisor 39 and the new remainder 11,and apply the division lemma to get
39 = 11 x 3 + 6
We consider the new divisor 11 and the new remainder 6,and apply the division lemma to get
11 = 6 x 1 + 5
We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get
6 = 5 x 1 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 545 and 317 is 1
Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(11,6) = HCF(39,11) = HCF(50,39) = HCF(89,50) = HCF(228,89) = HCF(317,228) = HCF(545,317) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 860 > 1, we apply the division lemma to 860 and 1, to get
860 = 1 x 860 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 860 is 1
Notice that 1 = HCF(860,1) .
