HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 786, 672, 581 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 786, 672, 581 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 786, 672, 581 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 786, 672, 581 is 1.
HCF(786, 672, 581) = 1
HCF of 786, 672, 581 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 786, 672, 581 is 1.
Highest Common Factor of 786,672,581 is 1
Step 1: Since 786 > 672, we apply the division lemma to 786 and 672, to get
786 = 672 x 1 + 114
Step 2: Since the reminder 672 ≠ 0, we apply division lemma to 114 and 672, to get
672 = 114 x 5 + 102
Step 3: We consider the new divisor 114 and the new remainder 102, and apply the division lemma to get
114 = 102 x 1 + 12
We consider the new divisor 102 and the new remainder 12,and apply the division lemma to get
102 = 12 x 8 + 6
We consider the new divisor 12 and the new remainder 6,and apply the division lemma to get
12 = 6 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 786 and 672 is 6
Notice that 6 = HCF(12,6) = HCF(102,12) = HCF(114,102) = HCF(672,114) = HCF(786,672) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 581 > 6, we apply the division lemma to 581 and 6, to get
581 = 6 x 96 + 5
Step 2: Since the reminder 6 ≠ 0, we apply division lemma to 5 and 6, to get
6 = 5 x 1 + 1
Step 3: We consider the new divisor 5 and the new remainder 1, and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 6 and 581 is 1
Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(581,6) .
