HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 8142, 787 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 8142, 787 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 8142, 787 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 8142, 787 is 1.
HCF(8142, 787) = 1
HCF of 8142, 787 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 8142, 787 is 1.
Highest Common Factor of 8142,787 is 1
Step 1: Since 8142 > 787, we apply the division lemma to 8142 and 787, to get
8142 = 787 x 10 + 272
Step 2: Since the reminder 787 ≠ 0, we apply division lemma to 272 and 787, to get
787 = 272 x 2 + 243
Step 3: We consider the new divisor 272 and the new remainder 243, and apply the division lemma to get
272 = 243 x 1 + 29
We consider the new divisor 243 and the new remainder 29,and apply the division lemma to get
243 = 29 x 8 + 11
We consider the new divisor 29 and the new remainder 11,and apply the division lemma to get
29 = 11 x 2 + 7
We consider the new divisor 11 and the new remainder 7,and apply the division lemma to get
11 = 7 x 1 + 4
We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get
7 = 4 x 1 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 8142 and 787 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(11,7) = HCF(29,11) = HCF(243,29) = HCF(272,243) = HCF(787,272) = HCF(8142,787) .
