HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 474, 340, 816 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 474, 340, 816 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 474, 340, 816 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 474, 340, 816 is 2.
HCF(474, 340, 816) = 2
HCF of 474, 340, 816 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 474, 340, 816 is 2.
Highest Common Factor of 474,340,816 is 2
Step 1: Since 474 > 340, we apply the division lemma to 474 and 340, to get
474 = 340 x 1 + 134
Step 2: Since the reminder 340 ≠ 0, we apply division lemma to 134 and 340, to get
340 = 134 x 2 + 72
Step 3: We consider the new divisor 134 and the new remainder 72, and apply the division lemma to get
134 = 72 x 1 + 62
We consider the new divisor 72 and the new remainder 62,and apply the division lemma to get
72 = 62 x 1 + 10
We consider the new divisor 62 and the new remainder 10,and apply the division lemma to get
62 = 10 x 6 + 2
We consider the new divisor 10 and the new remainder 2,and apply the division lemma to get
10 = 2 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 474 and 340 is 2
Notice that 2 = HCF(10,2) = HCF(62,10) = HCF(72,62) = HCF(134,72) = HCF(340,134) = HCF(474,340) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 816 > 2, we apply the division lemma to 816 and 2, to get
816 = 2 x 408 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 816 is 2
Notice that 2 = HCF(816,2) .
