HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 864, 135, 917 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 864, 135, 917 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 864, 135, 917 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 864, 135, 917 is 1.
HCF(864, 135, 917) = 1
HCF of 864, 135, 917 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 864, 135, 917 is 1.
Highest Common Factor of 864,135,917 is 1
Step 1: Since 864 > 135, we apply the division lemma to 864 and 135, to get
864 = 135 x 6 + 54
Step 2: Since the reminder 135 ≠ 0, we apply division lemma to 54 and 135, to get
135 = 54 x 2 + 27
Step 3: We consider the new divisor 54 and the new remainder 27, and apply the division lemma to get
54 = 27 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 27, the HCF of 864 and 135 is 27
Notice that 27 = HCF(54,27) = HCF(135,54) = HCF(864,135) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 917 > 27, we apply the division lemma to 917 and 27, to get
917 = 27 x 33 + 26
Step 2: Since the reminder 27 ≠ 0, we apply division lemma to 26 and 27, to get
27 = 26 x 1 + 1
Step 3: We consider the new divisor 26 and the new remainder 1, and apply the division lemma to get
26 = 1 x 26 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 27 and 917 is 1
Notice that 1 = HCF(26,1) = HCF(27,26) = HCF(917,27) .
