HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 864, 70908 i.e. 12 the largest integer that leaves a remainder zero for all numbers.
HCF of 864, 70908 is 12 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 864, 70908 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 864, 70908 is 12.
HCF(864, 70908) = 12
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 864, 70908 is 12.
Step 1: Since 70908 > 864, we apply the division lemma to 70908 and 864, to get
70908 = 864 x 82 + 60
Step 2: Since the reminder 864 ≠ 0, we apply division lemma to 60 and 864, to get
864 = 60 x 14 + 24
Step 3: We consider the new divisor 60 and the new remainder 24, and apply the division lemma to get
60 = 24 x 2 + 12
We consider the new divisor 24 and the new remainder 12, and apply the division lemma to get
24 = 12 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 12, the HCF of 864 and 70908 is 12
Notice that 12 = HCF(24,12) = HCF(60,24) = HCF(864,60) = HCF(70908,864) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
