HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 637, 881, 39 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 637, 881, 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 637, 881, 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 637, 881, 39 is 1.
HCF(637, 881, 39) = 1
HCF of 637, 881, 39 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 637, 881, 39 is 1.
Highest Common Factor of 637,881,39 is 1
Step 1: Since 881 > 637, we apply the division lemma to 881 and 637, to get
881 = 637 x 1 + 244
Step 2: Since the reminder 637 ≠ 0, we apply division lemma to 244 and 637, to get
637 = 244 x 2 + 149
Step 3: We consider the new divisor 244 and the new remainder 149, and apply the division lemma to get
244 = 149 x 1 + 95
We consider the new divisor 149 and the new remainder 95,and apply the division lemma to get
149 = 95 x 1 + 54
We consider the new divisor 95 and the new remainder 54,and apply the division lemma to get
95 = 54 x 1 + 41
We consider the new divisor 54 and the new remainder 41,and apply the division lemma to get
54 = 41 x 1 + 13
We consider the new divisor 41 and the new remainder 13,and apply the division lemma to get
41 = 13 x 3 + 2
We consider the new divisor 13 and the new remainder 2,and apply the division lemma to get
13 = 2 x 6 + 1
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 637 and 881 is 1
Notice that 1 = HCF(2,1) = HCF(13,2) = HCF(41,13) = HCF(54,41) = HCF(95,54) = HCF(149,95) = HCF(244,149) = HCF(637,244) = HCF(881,637) .
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) .
