HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 330, 128, 790 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 330, 128, 790 is 2 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 330, 128, 790 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 330, 128, 790 is 2.
HCF(330, 128, 790) = 2
HCF of 330, 128, 790 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 330, 128, 790 is 2.
Highest Common Factor of 330,128,790 is 2
Step 1: Since 330 > 128, we apply the division lemma to 330 and 128, to get
330 = 128 x 2 + 74
Step 2: Since the reminder 128 ≠ 0, we apply division lemma to 74 and 128, to get
128 = 74 x 1 + 54
Step 3: We consider the new divisor 74 and the new remainder 54, and apply the division lemma to get
74 = 54 x 1 + 20
We consider the new divisor 54 and the new remainder 20,and apply the division lemma to get
54 = 20 x 2 + 14
We consider the new divisor 20 and the new remainder 14,and apply the division lemma to get
20 = 14 x 1 + 6
We consider the new divisor 14 and the new remainder 6,and apply the division lemma to get
14 = 6 x 2 + 2
We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get
6 = 2 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 330 and 128 is 2
Notice that 2 = HCF(6,2) = HCF(14,6) = HCF(20,14) = HCF(54,20) = HCF(74,54) = HCF(128,74) = HCF(330,128) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 790 > 2, we apply the division lemma to 790 and 2, to get
790 = 2 x 395 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 790 is 2
Notice that 2 = HCF(790,2) .
