HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 973, 402, 290 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 973, 402, 290 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 973, 402, 290 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 973, 402, 290 is 1.
HCF(973, 402, 290) = 1
HCF of 973, 402, 290 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 973, 402, 290 is 1.
Highest Common Factor of 973,402,290 is 1
Step 1: Since 973 > 402, we apply the division lemma to 973 and 402, to get
973 = 402 x 2 + 169
Step 2: Since the reminder 402 ≠ 0, we apply division lemma to 169 and 402, to get
402 = 169 x 2 + 64
Step 3: We consider the new divisor 169 and the new remainder 64, and apply the division lemma to get
169 = 64 x 2 + 41
We consider the new divisor 64 and the new remainder 41,and apply the division lemma to get
64 = 41 x 1 + 23
We consider the new divisor 41 and the new remainder 23,and apply the division lemma to get
41 = 23 x 1 + 18
We consider the new divisor 23 and the new remainder 18,and apply the division lemma to get
23 = 18 x 1 + 5
We consider the new divisor 18 and the new remainder 5,and apply the division lemma to get
18 = 5 x 3 + 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 973 and 402 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(18,5) = HCF(23,18) = HCF(41,23) = HCF(64,41) = HCF(169,64) = HCF(402,169) = HCF(973,402) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 290 > 1, we apply the division lemma to 290 and 1, to get
290 = 1 x 290 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 290 is 1
Notice that 1 = HCF(290,1) .
