HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 427, 814, 724, 856 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 427, 814, 724, 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 427, 814, 724, 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 427, 814, 724, 856 is 1.
HCF(427, 814, 724, 856) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 427, 814, 724, 856 is 1.
Step 1: Since 814 > 427, we apply the division lemma to 814 and 427, to get
814 = 427 x 1 + 387
Step 2: Since the reminder 427 ≠ 0, we apply division lemma to 387 and 427, to get
427 = 387 x 1 + 40
Step 3: We consider the new divisor 387 and the new remainder 40, and apply the division lemma to get
387 = 40 x 9 + 27
We consider the new divisor 40 and the new remainder 27,and apply the division lemma to get
40 = 27 x 1 + 13
We consider the new divisor 27 and the new remainder 13,and apply the division lemma to get
27 = 13 x 2 + 1
We consider the new divisor 13 and the new remainder 1,and apply the division lemma to get
13 = 1 x 13 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 427 and 814 is 1
Notice that 1 = HCF(13,1) = HCF(27,13) = HCF(40,27) = HCF(387,40) = HCF(427,387) = HCF(814,427) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 724 > 1, we apply the division lemma to 724 and 1, to get
724 = 1 x 724 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 724 is 1
Notice that 1 = HCF(724,1) .
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) .
Here are some samples of HCF using Euclid's Algorithm calculations.
