HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 744, 384, 105 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 744, 384, 105 is 3 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 744, 384, 105 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 744, 384, 105 is 3.
HCF(744, 384, 105) = 3
HCF of 744, 384, 105 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 744, 384, 105 is 3.
Highest Common Factor of 744,384,105 is 3
Step 1: Since 744 > 384, we apply the division lemma to 744 and 384, to get
744 = 384 x 1 + 360
Step 2: Since the reminder 384 ≠ 0, we apply division lemma to 360 and 384, to get
384 = 360 x 1 + 24
Step 3: We consider the new divisor 360 and the new remainder 24, and apply the division lemma to get
360 = 24 x 15 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 24, the HCF of 744 and 384 is 24
Notice that 24 = HCF(360,24) = HCF(384,360) = HCF(744,384) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 105 > 24, we apply the division lemma to 105 and 24, to get
105 = 24 x 4 + 9
Step 2: Since the reminder 24 ≠ 0, we apply division lemma to 9 and 24, to get
24 = 9 x 2 + 6
Step 3: We consider the new divisor 9 and the new remainder 6, and apply the division lemma to get
9 = 6 x 1 + 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 24 and 105 is 3
Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(24,9) = HCF(105,24) .
