HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 309, 276, 816, 22 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 309, 276, 816, 22 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 309, 276, 816, 22 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 309, 276, 816, 22 is 1.
HCF(309, 276, 816, 22) = 1
HCF of 309, 276, 816, 22 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 309, 276, 816, 22 is 1.
Highest Common Factor of 309,276,816,22 is 1
Step 1: Since 309 > 276, we apply the division lemma to 309 and 276, to get
309 = 276 x 1 + 33
Step 2: Since the reminder 276 ≠ 0, we apply division lemma to 33 and 276, to get
276 = 33 x 8 + 12
Step 3: We consider the new divisor 33 and the new remainder 12, and apply the division lemma to get
33 = 12 x 2 + 9
We consider the new divisor 12 and the new remainder 9,and apply the division lemma to get
12 = 9 x 1 + 3
We consider the new divisor 9 and the new remainder 3,and apply the division lemma to get
9 = 3 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 309 and 276 is 3
Notice that 3 = HCF(9,3) = HCF(12,9) = HCF(33,12) = HCF(276,33) = HCF(309,276) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 816 > 3, we apply the division lemma to 816 and 3, to get
816 = 3 x 272 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 816 is 3
Notice that 3 = HCF(816,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 22 > 3, we apply the division lemma to 22 and 3, to get
22 = 3 x 7 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 22 is 1
Notice that 1 = HCF(3,1) = HCF(22,3) .
