HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 65, 78, 48, 6 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 65, 78, 48, 6 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 65, 78, 48, 6 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 65, 78, 48, 6 is 1.
HCF(65, 78, 48, 6) = 1
HCF of 65, 78, 48, 6 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 65, 78, 48, 6 is 1.
Highest Common Factor of 65,78,48,6 is 1
Step 1: Since 78 > 65, we apply the division lemma to 78 and 65, to get
78 = 65 x 1 + 13
Step 2: Since the reminder 65 ≠ 0, we apply division lemma to 13 and 65, to get
65 = 13 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 13, the HCF of 65 and 78 is 13
Notice that 13 = HCF(65,13) = HCF(78,65) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 48 > 13, we apply the division lemma to 48 and 13, to get
48 = 13 x 3 + 9
Step 2: Since the reminder 13 ≠ 0, we apply division lemma to 9 and 13, to get
13 = 9 x 1 + 4
Step 3: We consider the new divisor 9 and the new remainder 4, and apply the division lemma to get
9 = 4 x 2 + 1
We consider the new divisor 4 and the new remainder 1, and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 13 and 48 is 1
Notice that 1 = HCF(4,1) = HCF(9,4) = HCF(13,9) = HCF(48,13) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 6 > 1, we apply the division lemma to 6 and 1, to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 6 is 1
Notice that 1 = HCF(6,1) .
