HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 486, 672, 384 i.e. 6 the largest integer that leaves a remainder zero for all numbers.
HCF of 486, 672, 384 is 6 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 486, 672, 384 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 486, 672, 384 is 6.
HCF(486, 672, 384) = 6
HCF of 486, 672, 384 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 486, 672, 384 is 6.
Highest Common Factor of 486,672,384 is 6
Step 1: Since 672 > 486, we apply the division lemma to 672 and 486, to get
672 = 486 x 1 + 186
Step 2: Since the reminder 486 ≠ 0, we apply division lemma to 186 and 486, to get
486 = 186 x 2 + 114
Step 3: We consider the new divisor 186 and the new remainder 114, and apply the division lemma to get
186 = 114 x 1 + 72
We consider the new divisor 114 and the new remainder 72,and apply the division lemma to get
114 = 72 x 1 + 42
We consider the new divisor 72 and the new remainder 42,and apply the division lemma to get
72 = 42 x 1 + 30
We consider the new divisor 42 and the new remainder 30,and apply the division lemma to get
42 = 30 x 1 + 12
We consider the new divisor 30 and the new remainder 12,and apply the division lemma to get
30 = 12 x 2 + 6
We consider the new divisor 12 and the new remainder 6,and apply the division lemma to get
12 = 6 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 486 and 672 is 6
Notice that 6 = HCF(12,6) = HCF(30,12) = HCF(42,30) = HCF(72,42) = HCF(114,72) = HCF(186,114) = HCF(486,186) = HCF(672,486) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 384 > 6, we apply the division lemma to 384 and 6, to get
384 = 6 x 64 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 6 and 384 is 6
Notice that 6 = HCF(384,6) .
