HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 149, 826, 438, 13 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 149, 826, 438, 13 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 149, 826, 438, 13 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 149, 826, 438, 13 is 1.
HCF(149, 826, 438, 13) = 1
HCF of 149, 826, 438, 13 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 149, 826, 438, 13 is 1.
Highest Common Factor of 149,826,438,13 is 1
Step 1: Since 826 > 149, we apply the division lemma to 826 and 149, to get
826 = 149 x 5 + 81
Step 2: Since the reminder 149 ≠ 0, we apply division lemma to 81 and 149, to get
149 = 81 x 1 + 68
Step 3: We consider the new divisor 81 and the new remainder 68, and apply the division lemma to get
81 = 68 x 1 + 13
We consider the new divisor 68 and the new remainder 13,and apply the division lemma to get
68 = 13 x 5 + 3
We consider the new divisor 13 and the new remainder 3,and apply the division lemma to get
13 = 3 x 4 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma 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 149 and 826 is 1
Notice that 1 = HCF(3,1) = HCF(13,3) = HCF(68,13) = HCF(81,68) = HCF(149,81) = HCF(826,149) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 438 > 1, we apply the division lemma to 438 and 1, to get
438 = 1 x 438 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 438 is 1
Notice that 1 = HCF(438,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 13 > 1, we apply the division lemma to 13 and 1, to get
13 = 1 x 13 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 13 is 1
Notice that 1 = HCF(13,1) .
