HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 438, 266, 311 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 438, 266, 311 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 438, 266, 311 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 438, 266, 311 is 1.
HCF(438, 266, 311) = 1
HCF of 438, 266, 311 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 438, 266, 311 is 1.
Highest Common Factor of 438,266,311 is 1
Step 1: Since 438 > 266, we apply the division lemma to 438 and 266, to get
438 = 266 x 1 + 172
Step 2: Since the reminder 266 ≠ 0, we apply division lemma to 172 and 266, to get
266 = 172 x 1 + 94
Step 3: We consider the new divisor 172 and the new remainder 94, and apply the division lemma to get
172 = 94 x 1 + 78
We consider the new divisor 94 and the new remainder 78,and apply the division lemma to get
94 = 78 x 1 + 16
We consider the new divisor 78 and the new remainder 16,and apply the division lemma to get
78 = 16 x 4 + 14
We consider the new divisor 16 and the new remainder 14,and apply the division lemma to get
16 = 14 x 1 + 2
We consider the new divisor 14 and the new remainder 2,and apply the division lemma to get
14 = 2 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 438 and 266 is 2
Notice that 2 = HCF(14,2) = HCF(16,14) = HCF(78,16) = HCF(94,78) = HCF(172,94) = HCF(266,172) = HCF(438,266) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 311 > 2, we apply the division lemma to 311 and 2, to get
311 = 2 x 155 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 311 is 1
Notice that 1 = HCF(2,1) = HCF(311,2) .
