HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 468, 70806 i.e. 6 the largest integer that leaves a remainder zero for all numbers.
HCF of 468, 70806 is 6 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 468, 70806 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 468, 70806 is 6.
HCF(468, 70806) = 6
HCF of 468, 70806 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 468, 70806 is 6.
Highest Common Factor of 468,70806 is 6
Step 1: Since 70806 > 468, we apply the division lemma to 70806 and 468, to get
70806 = 468 x 151 + 138
Step 2: Since the reminder 468 ≠ 0, we apply division lemma to 138 and 468, to get
468 = 138 x 3 + 54
Step 3: We consider the new divisor 138 and the new remainder 54, and apply the division lemma to get
138 = 54 x 2 + 30
We consider the new divisor 54 and the new remainder 30,and apply the division lemma to get
54 = 30 x 1 + 24
We consider the new divisor 30 and the new remainder 24,and apply the division lemma to get
30 = 24 x 1 + 6
We consider the new divisor 24 and the new remainder 6,and apply the division lemma to get
24 = 6 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 468 and 70806 is 6
Notice that 6 = HCF(24,6) = HCF(30,24) = HCF(54,30) = HCF(138,54) = HCF(468,138) = HCF(70806,468) .
