HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 489, 456, 347 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 489, 456, 347 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 489, 456, 347 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 489, 456, 347 is 1.
HCF(489, 456, 347) = 1
HCF of 489, 456, 347 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 489, 456, 347 is 1.
Highest Common Factor of 489,456,347 is 1
Step 1: Since 489 > 456, we apply the division lemma to 489 and 456, to get
489 = 456 x 1 + 33
Step 2: Since the reminder 456 ≠ 0, we apply division lemma to 33 and 456, to get
456 = 33 x 13 + 27
Step 3: We consider the new divisor 33 and the new remainder 27, and apply the division lemma to get
33 = 27 x 1 + 6
We consider the new divisor 27 and the new remainder 6,and apply the division lemma to get
27 = 6 x 4 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 489 and 456 is 3
Notice that 3 = HCF(6,3) = HCF(27,6) = HCF(33,27) = HCF(456,33) = HCF(489,456) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 347 > 3, we apply the division lemma to 347 and 3, to get
347 = 3 x 115 + 2
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get
3 = 2 x 1 + 1
Step 3: 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 3 and 347 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(347,3) .
