HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 790, 240, 480 i.e. 10 the largest integer that leaves a remainder zero for all numbers.
HCF of 790, 240, 480 is 10 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 790, 240, 480 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 790, 240, 480 is 10.
HCF(790, 240, 480) = 10
HCF of 790, 240, 480 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 790, 240, 480 is 10.
Highest Common Factor of 790,240,480 is 10
Step 1: Since 790 > 240, we apply the division lemma to 790 and 240, to get
790 = 240 x 3 + 70
Step 2: Since the reminder 240 ≠ 0, we apply division lemma to 70 and 240, to get
240 = 70 x 3 + 30
Step 3: We consider the new divisor 70 and the new remainder 30, and apply the division lemma to get
70 = 30 x 2 + 10
We consider the new divisor 30 and the new remainder 10, and apply the division lemma to get
30 = 10 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 10, the HCF of 790 and 240 is 10
Notice that 10 = HCF(30,10) = HCF(70,30) = HCF(240,70) = HCF(790,240) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 480 > 10, we apply the division lemma to 480 and 10, to get
480 = 10 x 48 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 10, the HCF of 10 and 480 is 10
Notice that 10 = HCF(480,10) .
