HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 95, 78, 13, 280 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 95, 78, 13, 280 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 95, 78, 13, 280 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 95, 78, 13, 280 is 1.
HCF(95, 78, 13, 280) = 1
HCF of 95, 78, 13, 280 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 95, 78, 13, 280 is 1.
Highest Common Factor of 95,78,13,280 is 1
Step 1: Since 95 > 78, we apply the division lemma to 95 and 78, to get
95 = 78 x 1 + 17
Step 2: Since the reminder 78 ≠ 0, we apply division lemma to 17 and 78, to get
78 = 17 x 4 + 10
Step 3: We consider the new divisor 17 and the new remainder 10, and apply the division lemma to get
17 = 10 x 1 + 7
We consider the new divisor 10 and the new remainder 7,and apply the division lemma to get
10 = 7 x 1 + 3
We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get
7 = 3 x 2 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 95 and 78 is 1
Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(10,7) = HCF(17,10) = HCF(78,17) = HCF(95,78) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 13 > 1, we apply the division lemma to 13 and 1, to get
13 = 1 x 13 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 13 is 1
Notice that 1 = HCF(13,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 280 > 1, we apply the division lemma to 280 and 1, to get
280 = 1 x 280 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 280 is 1
Notice that 1 = HCF(280,1) .
