HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 780, 8786 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 780, 8786 is 2 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 780, 8786 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 780, 8786 is 2.
HCF(780, 8786) = 2
HCF of 780, 8786 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 780, 8786 is 2.
Highest Common Factor of 780,8786 is 2
Step 1: Since 8786 > 780, we apply the division lemma to 8786 and 780, to get
8786 = 780 x 11 + 206
Step 2: Since the reminder 780 ≠ 0, we apply division lemma to 206 and 780, to get
780 = 206 x 3 + 162
Step 3: We consider the new divisor 206 and the new remainder 162, and apply the division lemma to get
206 = 162 x 1 + 44
We consider the new divisor 162 and the new remainder 44,and apply the division lemma to get
162 = 44 x 3 + 30
We consider the new divisor 44 and the new remainder 30,and apply the division lemma to get
44 = 30 x 1 + 14
We consider the new divisor 30 and the new remainder 14,and apply the division lemma to get
30 = 14 x 2 + 2
We consider the new divisor 14 and the new remainder 2,and apply the division lemma to get
14 = 2 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 780 and 8786 is 2
Notice that 2 = HCF(14,2) = HCF(30,14) = HCF(44,30) = HCF(162,44) = HCF(206,162) = HCF(780,206) = HCF(8786,780) .
