HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 215, 583, 78 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 215, 583, 78 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 215, 583, 78 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 215, 583, 78 is 1.
HCF(215, 583, 78) = 1
HCF of 215, 583, 78 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 215, 583, 78 is 1.
Highest Common Factor of 215,583,78 is 1
Step 1: Since 583 > 215, we apply the division lemma to 583 and 215, to get
583 = 215 x 2 + 153
Step 2: Since the reminder 215 ≠ 0, we apply division lemma to 153 and 215, to get
215 = 153 x 1 + 62
Step 3: We consider the new divisor 153 and the new remainder 62, and apply the division lemma to get
153 = 62 x 2 + 29
We consider the new divisor 62 and the new remainder 29,and apply the division lemma to get
62 = 29 x 2 + 4
We consider the new divisor 29 and the new remainder 4,and apply the division lemma to get
29 = 4 x 7 + 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 215 and 583 is 1
Notice that 1 = HCF(4,1) = HCF(29,4) = HCF(62,29) = HCF(153,62) = HCF(215,153) = HCF(583,215) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 78 > 1, we apply the division lemma to 78 and 1, to get
78 = 1 x 78 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 78 is 1
Notice that 1 = HCF(78,1) .
