HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 84, 24, 395 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 84, 24, 395 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 84, 24, 395 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 84, 24, 395 is 1.
HCF(84, 24, 395) = 1
HCF of 84, 24, 395 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 84, 24, 395 is 1.
Highest Common Factor of 84,24,395 is 1
Step 1: Since 84 > 24, we apply the division lemma to 84 and 24, to get
84 = 24 x 3 + 12
Step 2: Since the reminder 24 ≠ 0, we apply division lemma to 12 and 24, 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 84 and 24 is 12
Notice that 12 = HCF(24,12) = HCF(84,24) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 395 > 12, we apply the division lemma to 395 and 12, to get
395 = 12 x 32 + 11
Step 2: Since the reminder 12 ≠ 0, we apply division lemma to 11 and 12, to get
12 = 11 x 1 + 1
Step 3: We consider the new divisor 11 and the new remainder 1, and apply the division lemma to get
11 = 1 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 12 and 395 is 1
Notice that 1 = HCF(11,1) = HCF(12,11) = HCF(395,12) .
