HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 345, 585, 856 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 345, 585, 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 345, 585, 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 345, 585, 856 is 1.
HCF(345, 585, 856) = 1
HCF of 345, 585, 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 345, 585, 856 is 1.
Highest Common Factor of 345,585,856 is 1
Step 1: Since 585 > 345, we apply the division lemma to 585 and 345, to get
585 = 345 x 1 + 240
Step 2: Since the reminder 345 ≠ 0, we apply division lemma to 240 and 345, to get
345 = 240 x 1 + 105
Step 3: We consider the new divisor 240 and the new remainder 105, and apply the division lemma to get
240 = 105 x 2 + 30
We consider the new divisor 105 and the new remainder 30,and apply the division lemma to get
105 = 30 x 3 + 15
We consider the new divisor 30 and the new remainder 15,and apply the division lemma to get
30 = 15 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 15, the HCF of 345 and 585 is 15
Notice that 15 = HCF(30,15) = HCF(105,30) = HCF(240,105) = HCF(345,240) = HCF(585,345) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 856 > 15, we apply the division lemma to 856 and 15, to get
856 = 15 x 57 + 1
Step 2: Since the reminder 15 ≠ 0, we apply division lemma to 1 and 15, to get
15 = 1 x 15 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 15 and 856 is 1
Notice that 1 = HCF(15,1) = HCF(856,15) .
