HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 406, 505, 994 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 406, 505, 994 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 406, 505, 994 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 406, 505, 994 is 1.
HCF(406, 505, 994) = 1
HCF of 406, 505, 994 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 406, 505, 994 is 1.
Highest Common Factor of 406,505,994 is 1
Step 1: Since 505 > 406, we apply the division lemma to 505 and 406, to get
505 = 406 x 1 + 99
Step 2: Since the reminder 406 ≠ 0, we apply division lemma to 99 and 406, to get
406 = 99 x 4 + 10
Step 3: We consider the new divisor 99 and the new remainder 10, and apply the division lemma to get
99 = 10 x 9 + 9
We consider the new divisor 10 and the new remainder 9,and apply the division lemma to get
10 = 9 x 1 + 1
We consider the new divisor 9 and the new remainder 1,and apply the division lemma to get
9 = 1 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 406 and 505 is 1
Notice that 1 = HCF(9,1) = HCF(10,9) = HCF(99,10) = HCF(406,99) = HCF(505,406) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 994 > 1, we apply the division lemma to 994 and 1, to get
994 = 1 x 994 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 994 is 1
Notice that 1 = HCF(994,1) .
