HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 43, 71, 637, 856 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 43, 71, 637, 856 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 43, 71, 637, 856 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 43, 71, 637, 856 is 1.
HCF(43, 71, 637, 856) = 1
HCF of 43, 71, 637, 856 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 43, 71, 637, 856 is 1.
Highest Common Factor of 43,71,637,856 is 1
Step 1: Since 71 > 43, we apply the division lemma to 71 and 43, to get
71 = 43 x 1 + 28
Step 2: Since the reminder 43 ≠ 0, we apply division lemma to 28 and 43, to get
43 = 28 x 1 + 15
Step 3: We consider the new divisor 28 and the new remainder 15, and apply the division lemma to get
28 = 15 x 1 + 13
We consider the new divisor 15 and the new remainder 13,and apply the division lemma to get
15 = 13 x 1 + 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 43 and 71 is 1
Notice that 1 = HCF(2,1) = HCF(13,2) = HCF(15,13) = HCF(28,15) = HCF(43,28) = HCF(71,43) .
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) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 856 > 1, we apply the division lemma to 856 and 1, to get
856 = 1 x 856 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 856 is 1
Notice that 1 = HCF(856,1) .
