HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 717, 547, 856 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 717, 547, 856 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 717, 547, 856 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 717, 547, 856 is 1.
HCF(717, 547, 856) = 1
HCF of 717, 547, 856 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 717, 547, 856 is 1.
Highest Common Factor of 717,547,856 is 1
Step 1: Since 717 > 547, we apply the division lemma to 717 and 547, to get
717 = 547 x 1 + 170
Step 2: Since the reminder 547 ≠ 0, we apply division lemma to 170 and 547, to get
547 = 170 x 3 + 37
Step 3: We consider the new divisor 170 and the new remainder 37, and apply the division lemma to get
170 = 37 x 4 + 22
We consider the new divisor 37 and the new remainder 22,and apply the division lemma to get
37 = 22 x 1 + 15
We consider the new divisor 22 and the new remainder 15,and apply the division lemma to get
22 = 15 x 1 + 7
We consider the new divisor 15 and the new remainder 7,and apply the division lemma to get
15 = 7 x 2 + 1
We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 717 and 547 is 1
Notice that 1 = HCF(7,1) = HCF(15,7) = HCF(22,15) = HCF(37,22) = HCF(170,37) = HCF(547,170) = HCF(717,547) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 856 > 1, we apply the division lemma to 856 and 1, to get
856 = 1 x 856 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 856 is 1
Notice that 1 = HCF(856,1) .
