HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 290, 389, 151 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 290, 389, 151 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 290, 389, 151 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 290, 389, 151 is 1.
HCF(290, 389, 151) = 1
HCF of 290, 389, 151 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 290, 389, 151 is 1.
Highest Common Factor of 290,389,151 is 1
Step 1: Since 389 > 290, we apply the division lemma to 389 and 290, to get
389 = 290 x 1 + 99
Step 2: Since the reminder 290 ≠ 0, we apply division lemma to 99 and 290, to get
290 = 99 x 2 + 92
Step 3: We consider the new divisor 99 and the new remainder 92, and apply the division lemma to get
99 = 92 x 1 + 7
We consider the new divisor 92 and the new remainder 7,and apply the division lemma to get
92 = 7 x 13 + 1
We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 290 and 389 is 1
Notice that 1 = HCF(7,1) = HCF(92,7) = HCF(99,92) = HCF(290,99) = HCF(389,290) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 151 > 1, we apply the division lemma to 151 and 1, to get
151 = 1 x 151 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 151 is 1
Notice that 1 = HCF(151,1) .
