HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 71, 28, 56, 850 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 71, 28, 56, 850 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 71, 28, 56, 850 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 71, 28, 56, 850 is 1.
HCF(71, 28, 56, 850) = 1
HCF of 71, 28, 56, 850 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 71, 28, 56, 850 is 1.
Highest Common Factor of 71,28,56,850 is 1
Step 1: Since 71 > 28, we apply the division lemma to 71 and 28, to get
71 = 28 x 2 + 15
Step 2: Since the reminder 28 ≠ 0, we apply division lemma to 15 and 28, to get
28 = 15 x 1 + 13
Step 3: 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 71 and 28 is 1
Notice that 1 = HCF(2,1) = HCF(13,2) = HCF(15,13) = HCF(28,15) = HCF(71,28) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 56 > 1, we apply the division lemma to 56 and 1, to get
56 = 1 x 56 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 56 is 1
Notice that 1 = HCF(56,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 850 > 1, we apply the division lemma to 850 and 1, to get
850 = 1 x 850 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 850 is 1
Notice that 1 = HCF(850,1) .
