HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 109, 279, 443, 997 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 109, 279, 443, 997 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 109, 279, 443, 997 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 109, 279, 443, 997 is 1.
HCF(109, 279, 443, 997) = 1
HCF of 109, 279, 443, 997 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 109, 279, 443, 997 is 1.
Highest Common Factor of 109,279,443,997 is 1
Step 1: Since 279 > 109, we apply the division lemma to 279 and 109, to get
279 = 109 x 2 + 61
Step 2: Since the reminder 109 ≠ 0, we apply division lemma to 61 and 109, to get
109 = 61 x 1 + 48
Step 3: We consider the new divisor 61 and the new remainder 48, and apply the division lemma to get
61 = 48 x 1 + 13
We consider the new divisor 48 and the new remainder 13,and apply the division lemma to get
48 = 13 x 3 + 9
We consider the new divisor 13 and the new remainder 9,and apply the division lemma to get
13 = 9 x 1 + 4
We consider the new divisor 9 and the new remainder 4,and apply the division lemma to get
9 = 4 x 2 + 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 109 and 279 is 1
Notice that 1 = HCF(4,1) = HCF(9,4) = HCF(13,9) = HCF(48,13) = HCF(61,48) = HCF(109,61) = HCF(279,109) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 443 > 1, we apply the division lemma to 443 and 1, to get
443 = 1 x 443 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 443 is 1
Notice that 1 = HCF(443,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 997 > 1, we apply the division lemma to 997 and 1, to get
997 = 1 x 997 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 997 is 1
Notice that 1 = HCF(997,1) .
