HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 676, 1854, 8186 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 676, 1854, 8186 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 676, 1854, 8186 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 676, 1854, 8186 is 2.
HCF(676, 1854, 8186) = 2
HCF of 676, 1854, 8186 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 676, 1854, 8186 is 2.
Highest Common Factor of 676,1854,8186 is 2
Step 1: Since 1854 > 676, we apply the division lemma to 1854 and 676, to get
1854 = 676 x 2 + 502
Step 2: Since the reminder 676 ≠ 0, we apply division lemma to 502 and 676, to get
676 = 502 x 1 + 174
Step 3: We consider the new divisor 502 and the new remainder 174, and apply the division lemma to get
502 = 174 x 2 + 154
We consider the new divisor 174 and the new remainder 154,and apply the division lemma to get
174 = 154 x 1 + 20
We consider the new divisor 154 and the new remainder 20,and apply the division lemma to get
154 = 20 x 7 + 14
We consider the new divisor 20 and the new remainder 14,and apply the division lemma to get
20 = 14 x 1 + 6
We consider the new divisor 14 and the new remainder 6,and apply the division lemma to get
14 = 6 x 2 + 2
We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get
6 = 2 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 676 and 1854 is 2
Notice that 2 = HCF(6,2) = HCF(14,6) = HCF(20,14) = HCF(154,20) = HCF(174,154) = HCF(502,174) = HCF(676,502) = HCF(1854,676) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 8186 > 2, we apply the division lemma to 8186 and 2, to get
8186 = 2 x 4093 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 8186 is 2
Notice that 2 = HCF(8186,2) .
