HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 287, 467, 100 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 287, 467, 100 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 287, 467, 100 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 287, 467, 100 is 1.
HCF(287, 467, 100) = 1
HCF of 287, 467, 100 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 287, 467, 100 is 1.
Highest Common Factor of 287,467,100 is 1
Step 1: Since 467 > 287, we apply the division lemma to 467 and 287, to get
467 = 287 x 1 + 180
Step 2: Since the reminder 287 ≠ 0, we apply division lemma to 180 and 287, to get
287 = 180 x 1 + 107
Step 3: We consider the new divisor 180 and the new remainder 107, and apply the division lemma to get
180 = 107 x 1 + 73
We consider the new divisor 107 and the new remainder 73,and apply the division lemma to get
107 = 73 x 1 + 34
We consider the new divisor 73 and the new remainder 34,and apply the division lemma to get
73 = 34 x 2 + 5
We consider the new divisor 34 and the new remainder 5,and apply the division lemma to get
34 = 5 x 6 + 4
We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get
5 = 4 x 1 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 287 and 467 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(34,5) = HCF(73,34) = HCF(107,73) = HCF(180,107) = HCF(287,180) = HCF(467,287) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 100 > 1, we apply the division lemma to 100 and 1, to get
100 = 1 x 100 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 100 is 1
Notice that 1 = HCF(100,1) .
