HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 240, 290, 128 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 240, 290, 128 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 240, 290, 128 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 240, 290, 128 is 2.
HCF(240, 290, 128) = 2
HCF of 240, 290, 128 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 240, 290, 128 is 2.
Highest Common Factor of 240,290,128 is 2
Step 1: Since 290 > 240, we apply the division lemma to 290 and 240, to get
290 = 240 x 1 + 50
Step 2: Since the reminder 240 ≠ 0, we apply division lemma to 50 and 240, to get
240 = 50 x 4 + 40
Step 3: We consider the new divisor 50 and the new remainder 40, and apply the division lemma to get
50 = 40 x 1 + 10
We consider the new divisor 40 and the new remainder 10, and apply the division lemma to get
40 = 10 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 10, the HCF of 240 and 290 is 10
Notice that 10 = HCF(40,10) = HCF(50,40) = HCF(240,50) = HCF(290,240) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 128 > 10, we apply the division lemma to 128 and 10, to get
128 = 10 x 12 + 8
Step 2: Since the reminder 10 ≠ 0, we apply division lemma to 8 and 10, to get
10 = 8 x 1 + 2
Step 3: We consider the new divisor 8 and the new remainder 2, and apply the division lemma to get
8 = 2 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 10 and 128 is 2
Notice that 2 = HCF(8,2) = HCF(10,8) = HCF(128,10) .
