HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 39, 37, 31, 205 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 39, 37, 31, 205 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 39, 37, 31, 205 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 39, 37, 31, 205 is 1.
HCF(39, 37, 31, 205) = 1
HCF of 39, 37, 31, 205 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 39, 37, 31, 205 is 1.
Highest Common Factor of 39,37,31,205 is 1
Step 1: Since 39 > 37, we apply the division lemma to 39 and 37, to get
39 = 37 x 1 + 2
Step 2: Since the reminder 37 ≠ 0, we apply division lemma to 2 and 37, to get
37 = 2 x 18 + 1
Step 3: We consider the new divisor 2 and the new remainder 1, and apply the division lemma 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 39 and 37 is 1
Notice that 1 = HCF(2,1) = HCF(37,2) = HCF(39,37) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 31 > 1, we apply the division lemma to 31 and 1, to get
31 = 1 x 31 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 31 is 1
Notice that 1 = HCF(31,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 205 > 1, we apply the division lemma to 205 and 1, to get
205 = 1 x 205 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 205 is 1
Notice that 1 = HCF(205,1) .
