HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 521, 308, 290 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 521, 308, 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 521, 308, 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 521, 308, 290 is 1.
HCF(521, 308, 290) = 1
HCF of 521, 308, 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 521, 308, 290 is 1.
Highest Common Factor of 521,308,290 is 1
Step 1: Since 521 > 308, we apply the division lemma to 521 and 308, to get
521 = 308 x 1 + 213
Step 2: Since the reminder 308 ≠ 0, we apply division lemma to 213 and 308, to get
308 = 213 x 1 + 95
Step 3: We consider the new divisor 213 and the new remainder 95, and apply the division lemma to get
213 = 95 x 2 + 23
We consider the new divisor 95 and the new remainder 23,and apply the division lemma to get
95 = 23 x 4 + 3
We consider the new divisor 23 and the new remainder 3,and apply the division lemma to get
23 = 3 x 7 + 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 521 and 308 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(23,3) = HCF(95,23) = HCF(213,95) = HCF(308,213) = HCF(521,308) .
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) .
