HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 427, 968, 677, 431 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 427, 968, 677, 431 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, 968, 677, 431 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, 968, 677, 431 is 1.
HCF(427, 968, 677, 431) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 427, 968, 677, 431 is 1.
Step 1: Since 968 > 427, we apply the division lemma to 968 and 427, to get
968 = 427 x 2 + 114
Step 2: Since the reminder 427 ≠ 0, we apply division lemma to 114 and 427, to get
427 = 114 x 3 + 85
Step 3: We consider the new divisor 114 and the new remainder 85, and apply the division lemma to get
114 = 85 x 1 + 29
We consider the new divisor 85 and the new remainder 29,and apply the division lemma to get
85 = 29 x 2 + 27
We consider the new divisor 29 and the new remainder 27,and apply the division lemma to get
29 = 27 x 1 + 2
We consider the new divisor 27 and the new remainder 2,and apply the division lemma to get
27 = 2 x 13 + 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 427 and 968 is 1
Notice that 1 = HCF(2,1) = HCF(27,2) = HCF(29,27) = HCF(85,29) = HCF(114,85) = HCF(427,114) = HCF(968,427) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 677 > 1, we apply the division lemma to 677 and 1, to get
677 = 1 x 677 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 677 is 1
Notice that 1 = HCF(677,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 431 > 1, we apply the division lemma to 431 and 1, to get
431 = 1 x 431 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 431 is 1
Notice that 1 = HCF(431,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
