HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 989, 506, 982 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 989, 506, 982 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, 506, 982 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, 506, 982 is 1.
HCF(989, 506, 982) = 1
HCF of 989, 506, 982 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, 506, 982 is 1.
Highest Common Factor of 989,506,982 is 1
Step 1: Since 989 > 506, we apply the division lemma to 989 and 506, to get
989 = 506 x 1 + 483
Step 2: Since the reminder 506 ≠ 0, we apply division lemma to 483 and 506, to get
506 = 483 x 1 + 23
Step 3: We consider the new divisor 483 and the new remainder 23, and apply the division lemma to get
483 = 23 x 21 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 23, the HCF of 989 and 506 is 23
Notice that 23 = HCF(483,23) = HCF(506,483) = HCF(989,506) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 982 > 23, we apply the division lemma to 982 and 23, to get
982 = 23 x 42 + 16
Step 2: Since the reminder 23 ≠ 0, we apply division lemma to 16 and 23, to get
23 = 16 x 1 + 7
Step 3: We consider the new divisor 16 and the new remainder 7, and apply the division lemma to get
16 = 7 x 2 + 2
We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get
7 = 2 x 3 + 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 23 and 982 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(16,7) = HCF(23,16) = HCF(982,23) .
