HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 172, 580, 818 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 172, 580, 818 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 172, 580, 818 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 172, 580, 818 is 2.
HCF(172, 580, 818) = 2
HCF of 172, 580, 818 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 172, 580, 818 is 2.
Highest Common Factor of 172,580,818 is 2
Step 1: Since 580 > 172, we apply the division lemma to 580 and 172, to get
580 = 172 x 3 + 64
Step 2: Since the reminder 172 ≠ 0, we apply division lemma to 64 and 172, to get
172 = 64 x 2 + 44
Step 3: We consider the new divisor 64 and the new remainder 44, and apply the division lemma to get
64 = 44 x 1 + 20
We consider the new divisor 44 and the new remainder 20,and apply the division lemma to get
44 = 20 x 2 + 4
We consider the new divisor 20 and the new remainder 4,and apply the division lemma to get
20 = 4 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 172 and 580 is 4
Notice that 4 = HCF(20,4) = HCF(44,20) = HCF(64,44) = HCF(172,64) = HCF(580,172) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 818 > 4, we apply the division lemma to 818 and 4, to get
818 = 4 x 204 + 2
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 2 and 4, to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 4 and 818 is 2
Notice that 2 = HCF(4,2) = HCF(818,4) .
