HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 8430, 868 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 8430, 868 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 8430, 868 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 8430, 868 is 2.
HCF(8430, 868) = 2
HCF of 8430, 868 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 8430, 868 is 2.
Highest Common Factor of 8430,868 is 2
Step 1: Since 8430 > 868, we apply the division lemma to 8430 and 868, to get
8430 = 868 x 9 + 618
Step 2: Since the reminder 868 ≠ 0, we apply division lemma to 618 and 868, to get
868 = 618 x 1 + 250
Step 3: We consider the new divisor 618 and the new remainder 250, and apply the division lemma to get
618 = 250 x 2 + 118
We consider the new divisor 250 and the new remainder 118,and apply the division lemma to get
250 = 118 x 2 + 14
We consider the new divisor 118 and the new remainder 14,and apply the division lemma to get
118 = 14 x 8 + 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 8430 and 868 is 2
Notice that 2 = HCF(6,2) = HCF(14,6) = HCF(118,14) = HCF(250,118) = HCF(618,250) = HCF(868,618) = HCF(8430,868) .
