HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 78, 913, 610 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 78, 913, 610 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 78, 913, 610 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 78, 913, 610 is 1.
HCF(78, 913, 610) = 1
HCF of 78, 913, 610 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 78, 913, 610 is 1.
Highest Common Factor of 78,913,610 is 1
Step 1: Since 913 > 78, we apply the division lemma to 913 and 78, to get
913 = 78 x 11 + 55
Step 2: Since the reminder 78 ≠ 0, we apply division lemma to 55 and 78, to get
78 = 55 x 1 + 23
Step 3: We consider the new divisor 55 and the new remainder 23, and apply the division lemma to get
55 = 23 x 2 + 9
We consider the new divisor 23 and the new remainder 9,and apply the division lemma to get
23 = 9 x 2 + 5
We consider the new divisor 9 and the new remainder 5,and apply the division lemma to get
9 = 5 x 1 + 4
We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get
5 = 4 x 1 + 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 78 and 913 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(9,5) = HCF(23,9) = HCF(55,23) = HCF(78,55) = HCF(913,78) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 610 > 1, we apply the division lemma to 610 and 1, to get
610 = 1 x 610 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 610 is 1
Notice that 1 = HCF(610,1) .
