HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 994, 159, 398 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 994, 159, 398 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 994, 159, 398 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 994, 159, 398 is 1.
HCF(994, 159, 398) = 1
HCF of 994, 159, 398 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 994, 159, 398 is 1.
Highest Common Factor of 994,159,398 is 1
Step 1: Since 994 > 159, we apply the division lemma to 994 and 159, to get
994 = 159 x 6 + 40
Step 2: Since the reminder 159 ≠ 0, we apply division lemma to 40 and 159, to get
159 = 40 x 3 + 39
Step 3: We consider the new divisor 40 and the new remainder 39, and apply the division lemma to get
40 = 39 x 1 + 1
We consider the new divisor 39 and the new remainder 1, and apply the division lemma to get
39 = 1 x 39 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 994 and 159 is 1
Notice that 1 = HCF(39,1) = HCF(40,39) = HCF(159,40) = HCF(994,159) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 398 > 1, we apply the division lemma to 398 and 1, to get
398 = 1 x 398 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 398 is 1
Notice that 1 = HCF(398,1) .
