HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 15, 74, 34, 274 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 15, 74, 34, 274 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 15, 74, 34, 274 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 15, 74, 34, 274 is 1.
HCF(15, 74, 34, 274) = 1
HCF of 15, 74, 34, 274 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 15, 74, 34, 274 is 1.
Highest Common Factor of 15,74,34,274 is 1
Step 1: Since 74 > 15, we apply the division lemma to 74 and 15, to get
74 = 15 x 4 + 14
Step 2: Since the reminder 15 ≠ 0, we apply division lemma to 14 and 15, to get
15 = 14 x 1 + 1
Step 3: We consider the new divisor 14 and the new remainder 1, and apply the division lemma to get
14 = 1 x 14 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 15 and 74 is 1
Notice that 1 = HCF(14,1) = HCF(15,14) = HCF(74,15) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 34 > 1, we apply the division lemma to 34 and 1, to get
34 = 1 x 34 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 34 is 1
Notice that 1 = HCF(34,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 274 > 1, we apply the division lemma to 274 and 1, to get
274 = 1 x 274 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 274 is 1
Notice that 1 = HCF(274,1) .
