HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 859, 320, 817 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 859, 320, 817 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 859, 320, 817 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 859, 320, 817 is 1.
HCF(859, 320, 817) = 1
HCF of 859, 320, 817 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 859, 320, 817 is 1.
Highest Common Factor of 859,320,817 is 1
Step 1: Since 859 > 320, we apply the division lemma to 859 and 320, to get
859 = 320 x 2 + 219
Step 2: Since the reminder 320 ≠ 0, we apply division lemma to 219 and 320, to get
320 = 219 x 1 + 101
Step 3: We consider the new divisor 219 and the new remainder 101, and apply the division lemma to get
219 = 101 x 2 + 17
We consider the new divisor 101 and the new remainder 17,and apply the division lemma to get
101 = 17 x 5 + 16
We consider the new divisor 17 and the new remainder 16,and apply the division lemma to get
17 = 16 x 1 + 1
We consider the new divisor 16 and the new remainder 1,and apply the division lemma to get
16 = 1 x 16 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 859 and 320 is 1
Notice that 1 = HCF(16,1) = HCF(17,16) = HCF(101,17) = HCF(219,101) = HCF(320,219) = HCF(859,320) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 817 > 1, we apply the division lemma to 817 and 1, to get
817 = 1 x 817 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 817 is 1
Notice that 1 = HCF(817,1) .
