HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 383, 287, 69 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 383, 287, 69 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 383, 287, 69 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 383, 287, 69 is 1.
HCF(383, 287, 69) = 1
HCF of 383, 287, 69 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 383, 287, 69 is 1.
Highest Common Factor of 383,287,69 is 1
Step 1: Since 383 > 287, we apply the division lemma to 383 and 287, to get
383 = 287 x 1 + 96
Step 2: Since the reminder 287 ≠ 0, we apply division lemma to 96 and 287, to get
287 = 96 x 2 + 95
Step 3: We consider the new divisor 96 and the new remainder 95, and apply the division lemma to get
96 = 95 x 1 + 1
We consider the new divisor 95 and the new remainder 1, and apply the division lemma to get
95 = 1 x 95 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 383 and 287 is 1
Notice that 1 = HCF(95,1) = HCF(96,95) = HCF(287,96) = HCF(383,287) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 69 > 1, we apply the division lemma to 69 and 1, to get
69 = 1 x 69 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 69 is 1
Notice that 1 = HCF(69,1) .
