HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 261, 310, 637 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 261, 310, 637 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 261, 310, 637 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 261, 310, 637 is 1.
HCF(261, 310, 637) = 1
HCF of 261, 310, 637 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 261, 310, 637 is 1.
Highest Common Factor of 261,310,637 is 1
Step 1: Since 310 > 261, we apply the division lemma to 310 and 261, to get
310 = 261 x 1 + 49
Step 2: Since the reminder 261 ≠ 0, we apply division lemma to 49 and 261, to get
261 = 49 x 5 + 16
Step 3: We consider the new divisor 49 and the new remainder 16, and apply the division lemma to get
49 = 16 x 3 + 1
We consider the new divisor 16 and the new remainder 1, and apply the division lemma to get
16 = 1 x 16 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 261 and 310 is 1
Notice that 1 = HCF(16,1) = HCF(49,16) = HCF(261,49) = HCF(310,261) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 637 > 1, we apply the division lemma to 637 and 1, to get
637 = 1 x 637 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 637 is 1
Notice that 1 = HCF(637,1) .
