HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 970, 296, 489 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 970, 296, 489 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 970, 296, 489 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 970, 296, 489 is 1.
HCF(970, 296, 489) = 1
HCF of 970, 296, 489 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 970, 296, 489 is 1.
Highest Common Factor of 970,296,489 is 1
Step 1: Since 970 > 296, we apply the division lemma to 970 and 296, to get
970 = 296 x 3 + 82
Step 2: Since the reminder 296 ≠ 0, we apply division lemma to 82 and 296, to get
296 = 82 x 3 + 50
Step 3: We consider the new divisor 82 and the new remainder 50, and apply the division lemma to get
82 = 50 x 1 + 32
We consider the new divisor 50 and the new remainder 32,and apply the division lemma to get
50 = 32 x 1 + 18
We consider the new divisor 32 and the new remainder 18,and apply the division lemma to get
32 = 18 x 1 + 14
We consider the new divisor 18 and the new remainder 14,and apply the division lemma to get
18 = 14 x 1 + 4
We consider the new divisor 14 and the new remainder 4,and apply the division lemma to get
14 = 4 x 3 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 970 and 296 is 2
Notice that 2 = HCF(4,2) = HCF(14,4) = HCF(18,14) = HCF(32,18) = HCF(50,32) = HCF(82,50) = HCF(296,82) = HCF(970,296) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 489 > 2, we apply the division lemma to 489 and 2, to get
489 = 2 x 244 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 489 is 1
Notice that 1 = HCF(2,1) = HCF(489,2) .
