HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 510, 782, 931 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 510, 782, 931 is 1 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 510, 782, 931 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 510, 782, 931 is 1.
HCF(510, 782, 931) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 510, 782, 931 is 1.
Step 1: Since 782 > 510, we apply the division lemma to 782 and 510, to get
782 = 510 x 1 + 272
Step 2: Since the reminder 510 ≠ 0, we apply division lemma to 272 and 510, to get
510 = 272 x 1 + 238
Step 3: We consider the new divisor 272 and the new remainder 238, and apply the division lemma to get
272 = 238 x 1 + 34
We consider the new divisor 238 and the new remainder 34, and apply the division lemma to get
238 = 34 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 34, the HCF of 510 and 782 is 34
Notice that 34 = HCF(238,34) = HCF(272,238) = HCF(510,272) = HCF(782,510) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 931 > 34, we apply the division lemma to 931 and 34, to get
931 = 34 x 27 + 13
Step 2: Since the reminder 34 ≠ 0, we apply division lemma to 13 and 34, to get
34 = 13 x 2 + 8
Step 3: We consider the new divisor 13 and the new remainder 8, and apply the division lemma to get
13 = 8 x 1 + 5
We consider the new divisor 8 and the new remainder 5,and apply the division lemma to get
8 = 5 x 1 + 3
We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get
5 = 3 x 1 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 34 and 931 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(13,8) = HCF(34,13) = HCF(931,34) .
Here are some samples of HCF using Euclid's Algorithm calculations.
