HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 2718, 989 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 2718, 989 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 2718, 989 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 2718, 989 is 1.
HCF(2718, 989) = 1
HCF of 2718, 989 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 2718, 989 is 1.
Highest Common Factor of 2718,989 is 1
Step 1: Since 2718 > 989, we apply the division lemma to 2718 and 989, to get
2718 = 989 x 2 + 740
Step 2: Since the reminder 989 ≠ 0, we apply division lemma to 740 and 989, to get
989 = 740 x 1 + 249
Step 3: We consider the new divisor 740 and the new remainder 249, and apply the division lemma to get
740 = 249 x 2 + 242
We consider the new divisor 249 and the new remainder 242,and apply the division lemma to get
249 = 242 x 1 + 7
We consider the new divisor 242 and the new remainder 7,and apply the division lemma to get
242 = 7 x 34 + 4
We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get
7 = 4 x 1 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 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 2718 and 989 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(242,7) = HCF(249,242) = HCF(740,249) = HCF(989,740) = HCF(2718,989) .
