HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 428, 591, 815 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 428, 591, 815 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 428, 591, 815 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 428, 591, 815 is 1.
HCF(428, 591, 815) = 1
HCF of 428, 591, 815 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 428, 591, 815 is 1.
Highest Common Factor of 428,591,815 is 1
Step 1: Since 591 > 428, we apply the division lemma to 591 and 428, to get
591 = 428 x 1 + 163
Step 2: Since the reminder 428 ≠ 0, we apply division lemma to 163 and 428, to get
428 = 163 x 2 + 102
Step 3: We consider the new divisor 163 and the new remainder 102, and apply the division lemma to get
163 = 102 x 1 + 61
We consider the new divisor 102 and the new remainder 61,and apply the division lemma to get
102 = 61 x 1 + 41
We consider the new divisor 61 and the new remainder 41,and apply the division lemma to get
61 = 41 x 1 + 20
We consider the new divisor 41 and the new remainder 20,and apply the division lemma to get
41 = 20 x 2 + 1
We consider the new divisor 20 and the new remainder 1,and apply the division lemma to get
20 = 1 x 20 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 428 and 591 is 1
Notice that 1 = HCF(20,1) = HCF(41,20) = HCF(61,41) = HCF(102,61) = HCF(163,102) = HCF(428,163) = HCF(591,428) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 815 > 1, we apply the division lemma to 815 and 1, to get
815 = 1 x 815 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 815 is 1
Notice that 1 = HCF(815,1) .
