HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 794, 509 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 794, 509 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 794, 509 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 794, 509 is 1.
HCF(794, 509) = 1
HCF of 794, 509 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 794, 509 is 1.
Highest Common Factor of 794,509 is 1
Step 1: Since 794 > 509, we apply the division lemma to 794 and 509, to get
794 = 509 x 1 + 285
Step 2: Since the reminder 509 ≠ 0, we apply division lemma to 285 and 509, to get
509 = 285 x 1 + 224
Step 3: We consider the new divisor 285 and the new remainder 224, and apply the division lemma to get
285 = 224 x 1 + 61
We consider the new divisor 224 and the new remainder 61,and apply the division lemma to get
224 = 61 x 3 + 41
We consider the new divisor 61 and the new remainder 41,and apply the division lemma to get
61 = 41 x 1 + 20
We consider the new divisor 41 and the new remainder 20,and apply the division lemma to get
41 = 20 x 2 + 1
We consider the new divisor 20 and the new remainder 1,and apply the division lemma to get
20 = 1 x 20 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 794 and 509 is 1
Notice that 1 = HCF(20,1) = HCF(41,20) = HCF(61,41) = HCF(224,61) = HCF(285,224) = HCF(509,285) = HCF(794,509) .
