HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 456, 663, 319 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 456, 663, 319 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 456, 663, 319 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 456, 663, 319 is 1.
HCF(456, 663, 319) = 1
HCF of 456, 663, 319 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 456, 663, 319 is 1.
Highest Common Factor of 456,663,319 is 1
Step 1: Since 663 > 456, we apply the division lemma to 663 and 456, to get
663 = 456 x 1 + 207
Step 2: Since the reminder 456 ≠ 0, we apply division lemma to 207 and 456, to get
456 = 207 x 2 + 42
Step 3: We consider the new divisor 207 and the new remainder 42, and apply the division lemma to get
207 = 42 x 4 + 39
We consider the new divisor 42 and the new remainder 39,and apply the division lemma to get
42 = 39 x 1 + 3
We consider the new divisor 39 and the new remainder 3,and apply the division lemma to get
39 = 3 x 13 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 456 and 663 is 3
Notice that 3 = HCF(39,3) = HCF(42,39) = HCF(207,42) = HCF(456,207) = HCF(663,456) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 319 > 3, we apply the division lemma to 319 and 3, to get
319 = 3 x 106 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, 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 3 and 319 is 1
Notice that 1 = HCF(3,1) = HCF(319,3) .
