HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 315, 992, 354 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 315, 992, 354 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 315, 992, 354 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 315, 992, 354 is 1.
HCF(315, 992, 354) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 315, 992, 354 is 1.
Step 1: Since 992 > 315, we apply the division lemma to 992 and 315, to get
992 = 315 x 3 + 47
Step 2: Since the reminder 315 ≠ 0, we apply division lemma to 47 and 315, to get
315 = 47 x 6 + 33
Step 3: We consider the new divisor 47 and the new remainder 33, and apply the division lemma to get
47 = 33 x 1 + 14
We consider the new divisor 33 and the new remainder 14,and apply the division lemma to get
33 = 14 x 2 + 5
We consider the new divisor 14 and the new remainder 5,and apply the division lemma to get
14 = 5 x 2 + 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 315 and 992 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(14,5) = HCF(33,14) = HCF(47,33) = HCF(315,47) = HCF(992,315) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 354 > 1, we apply the division lemma to 354 and 1, to get
354 = 1 x 354 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 354 is 1
Notice that 1 = HCF(354,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
