HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 279, 443, 974 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 279, 443, 974 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 279, 443, 974 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 279, 443, 974 is 1.
HCF(279, 443, 974) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 279, 443, 974 is 1.
Step 1: Since 443 > 279, we apply the division lemma to 443 and 279, to get
443 = 279 x 1 + 164
Step 2: Since the reminder 279 ≠ 0, we apply division lemma to 164 and 279, to get
279 = 164 x 1 + 115
Step 3: We consider the new divisor 164 and the new remainder 115, and apply the division lemma to get
164 = 115 x 1 + 49
We consider the new divisor 115 and the new remainder 49,and apply the division lemma to get
115 = 49 x 2 + 17
We consider the new divisor 49 and the new remainder 17,and apply the division lemma to get
49 = 17 x 2 + 15
We consider the new divisor 17 and the new remainder 15,and apply the division lemma to get
17 = 15 x 1 + 2
We consider the new divisor 15 and the new remainder 2,and apply the division lemma to get
15 = 2 x 7 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 279 and 443 is 1
Notice that 1 = HCF(2,1) = HCF(15,2) = HCF(17,15) = HCF(49,17) = HCF(115,49) = HCF(164,115) = HCF(279,164) = HCF(443,279) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 974 > 1, we apply the division lemma to 974 and 1, to get
974 = 1 x 974 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 974 is 1
Notice that 1 = HCF(974,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
