HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 989, 79, 913 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 989, 79, 913 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 989, 79, 913 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 989, 79, 913 is 1.
HCF(989, 79, 913) = 1
HCF of 989, 79, 913 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 989, 79, 913 is 1.
Highest Common Factor of 989,79,913 is 1
Step 1: Since 989 > 79, we apply the division lemma to 989 and 79, to get
989 = 79 x 12 + 41
Step 2: Since the reminder 79 ≠ 0, we apply division lemma to 41 and 79, to get
79 = 41 x 1 + 38
Step 3: We consider the new divisor 41 and the new remainder 38, and apply the division lemma to get
41 = 38 x 1 + 3
We consider the new divisor 38 and the new remainder 3,and apply the division lemma to get
38 = 3 x 12 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 989 and 79 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(38,3) = HCF(41,38) = HCF(79,41) = HCF(989,79) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 913 > 1, we apply the division lemma to 913 and 1, to get
913 = 1 x 913 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 913 is 1
Notice that 1 = HCF(913,1) .
