HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 808, 787 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 808, 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 808, 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 808, 787 is 1.
HCF(808, 787) = 1
HCF of 808, 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 808, 787 is 1.
Highest Common Factor of 808,787 is 1
Step 1: Since 808 > 787, we apply the division lemma to 808 and 787, to get
808 = 787 x 1 + 21
Step 2: Since the reminder 787 ≠ 0, we apply division lemma to 21 and 787, to get
787 = 21 x 37 + 10
Step 3: We consider the new divisor 21 and the new remainder 10, and apply the division lemma to get
21 = 10 x 2 + 1
We consider the new divisor 10 and the new remainder 1, and apply the division lemma to get
10 = 1 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 808 and 787 is 1
Notice that 1 = HCF(10,1) = HCF(21,10) = HCF(787,21) = HCF(808,787) .
