HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 823, 979, 115, 354 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 823, 979, 115, 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 823, 979, 115, 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 823, 979, 115, 354 is 1.
HCF(823, 979, 115, 354) = 1
HCF of 823, 979, 115, 354 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 823, 979, 115, 354 is 1.
Highest Common Factor of 823,979,115,354 is 1
Step 1: Since 979 > 823, we apply the division lemma to 979 and 823, to get
979 = 823 x 1 + 156
Step 2: Since the reminder 823 ≠ 0, we apply division lemma to 156 and 823, to get
823 = 156 x 5 + 43
Step 3: We consider the new divisor 156 and the new remainder 43, and apply the division lemma to get
156 = 43 x 3 + 27
We consider the new divisor 43 and the new remainder 27,and apply the division lemma to get
43 = 27 x 1 + 16
We consider the new divisor 27 and the new remainder 16,and apply the division lemma to get
27 = 16 x 1 + 11
We consider the new divisor 16 and the new remainder 11,and apply the division lemma to get
16 = 11 x 1 + 5
We consider the new divisor 11 and the new remainder 5,and apply the division lemma to get
11 = 5 x 2 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 823 and 979 is 1
Notice that 1 = HCF(5,1) = HCF(11,5) = HCF(16,11) = HCF(27,16) = HCF(43,27) = HCF(156,43) = HCF(823,156) = HCF(979,823) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 115 > 1, we apply the division lemma to 115 and 1, to get
115 = 1 x 115 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 115 is 1
Notice that 1 = HCF(115,1) .
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) .
