HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 545, 897, 101 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 545, 897, 101 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, 897, 101 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, 897, 101 is 1.
HCF(545, 897, 101) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 545, 897, 101 is 1.
Step 1: Since 897 > 545, we apply the division lemma to 897 and 545, to get
897 = 545 x 1 + 352
Step 2: Since the reminder 545 ≠ 0, we apply division lemma to 352 and 545, to get
545 = 352 x 1 + 193
Step 3: We consider the new divisor 352 and the new remainder 193, and apply the division lemma to get
352 = 193 x 1 + 159
We consider the new divisor 193 and the new remainder 159,and apply the division lemma to get
193 = 159 x 1 + 34
We consider the new divisor 159 and the new remainder 34,and apply the division lemma to get
159 = 34 x 4 + 23
We consider the new divisor 34 and the new remainder 23,and apply the division lemma to get
34 = 23 x 1 + 11
We consider the new divisor 23 and the new remainder 11,and apply the division lemma to get
23 = 11 x 2 + 1
We consider the new divisor 11 and the new remainder 1,and apply the division lemma to get
11 = 1 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 545 and 897 is 1
Notice that 1 = HCF(11,1) = HCF(23,11) = HCF(34,23) = HCF(159,34) = HCF(193,159) = HCF(352,193) = HCF(545,352) = HCF(897,545) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 101 > 1, we apply the division lemma to 101 and 1, to get
101 = 1 x 101 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 101 is 1
Notice that 1 = HCF(101,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
