HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 786, 919, 811 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 786, 919, 811 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, 919, 811 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, 919, 811 is 1.
HCF(786, 919, 811) = 1
HCF of 786, 919, 811 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, 919, 811 is 1.
Highest Common Factor of 786,919,811 is 1
Step 1: Since 919 > 786, we apply the division lemma to 919 and 786, to get
919 = 786 x 1 + 133
Step 2: Since the reminder 786 ≠ 0, we apply division lemma to 133 and 786, to get
786 = 133 x 5 + 121
Step 3: We consider the new divisor 133 and the new remainder 121, and apply the division lemma to get
133 = 121 x 1 + 12
We consider the new divisor 121 and the new remainder 12,and apply the division lemma to get
121 = 12 x 10 + 1
We consider the new divisor 12 and the new remainder 1,and apply the division lemma to get
12 = 1 x 12 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 786 and 919 is 1
Notice that 1 = HCF(12,1) = HCF(121,12) = HCF(133,121) = HCF(786,133) = HCF(919,786) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 811 > 1, we apply the division lemma to 811 and 1, to get
811 = 1 x 811 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 811 is 1
Notice that 1 = HCF(811,1) .
