HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 151, 345, 298 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 151, 345, 298 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 151, 345, 298 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 151, 345, 298 is 1.
HCF(151, 345, 298) = 1
HCF of 151, 345, 298 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 151, 345, 298 is 1.
Highest Common Factor of 151,345,298 is 1
Step 1: Since 345 > 151, we apply the division lemma to 345 and 151, to get
345 = 151 x 2 + 43
Step 2: Since the reminder 151 ≠ 0, we apply division lemma to 43 and 151, to get
151 = 43 x 3 + 22
Step 3: We consider the new divisor 43 and the new remainder 22, and apply the division lemma to get
43 = 22 x 1 + 21
We consider the new divisor 22 and the new remainder 21,and apply the division lemma to get
22 = 21 x 1 + 1
We consider the new divisor 21 and the new remainder 1,and apply the division lemma to get
21 = 1 x 21 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 151 and 345 is 1
Notice that 1 = HCF(21,1) = HCF(22,21) = HCF(43,22) = HCF(151,43) = HCF(345,151) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 298 > 1, we apply the division lemma to 298 and 1, to get
298 = 1 x 298 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 298 is 1
Notice that 1 = HCF(298,1) .
