HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 437, 949, 39 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 437, 949, 39 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 437, 949, 39 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 437, 949, 39 is 1.
HCF(437, 949, 39) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 437, 949, 39 is 1.
Step 1: Since 949 > 437, we apply the division lemma to 949 and 437, to get
949 = 437 x 2 + 75
Step 2: Since the reminder 437 ≠ 0, we apply division lemma to 75 and 437, to get
437 = 75 x 5 + 62
Step 3: We consider the new divisor 75 and the new remainder 62, and apply the division lemma to get
75 = 62 x 1 + 13
We consider the new divisor 62 and the new remainder 13,and apply the division lemma to get
62 = 13 x 4 + 10
We consider the new divisor 13 and the new remainder 10,and apply the division lemma to get
13 = 10 x 1 + 3
We consider the new divisor 10 and the new remainder 3,and apply the division lemma to get
10 = 3 x 3 + 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 437 and 949 is 1
Notice that 1 = HCF(3,1) = HCF(10,3) = HCF(13,10) = HCF(62,13) = HCF(75,62) = HCF(437,75) = HCF(949,437) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 39 > 1, we apply the division lemma to 39 and 1, to get
39 = 1 x 39 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 39 is 1
Notice that 1 = HCF(39,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
