HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 857, 288, 399 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 857, 288, 399 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 857, 288, 399 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 857, 288, 399 is 1.
HCF(857, 288, 399) = 1
HCF of 857, 288, 399 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 857, 288, 399 is 1.
Highest Common Factor of 857,288,399 is 1
Step 1: Since 857 > 288, we apply the division lemma to 857 and 288, to get
857 = 288 x 2 + 281
Step 2: Since the reminder 288 ≠ 0, we apply division lemma to 281 and 288, to get
288 = 281 x 1 + 7
Step 3: We consider the new divisor 281 and the new remainder 7, and apply the division lemma to get
281 = 7 x 40 + 1
We consider the new divisor 7 and the new remainder 1, and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 857 and 288 is 1
Notice that 1 = HCF(7,1) = HCF(281,7) = HCF(288,281) = HCF(857,288) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 399 > 1, we apply the division lemma to 399 and 1, to get
399 = 1 x 399 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 399 is 1
Notice that 1 = HCF(399,1) .
