HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 380, 251, 550 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 380, 251, 550 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 380, 251, 550 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 380, 251, 550 is 1.
HCF(380, 251, 550) = 1
HCF of 380, 251, 550 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 380, 251, 550 is 1.
Highest Common Factor of 380,251,550 is 1
Step 1: Since 380 > 251, we apply the division lemma to 380 and 251, to get
380 = 251 x 1 + 129
Step 2: Since the reminder 251 ≠ 0, we apply division lemma to 129 and 251, to get
251 = 129 x 1 + 122
Step 3: We consider the new divisor 129 and the new remainder 122, and apply the division lemma to get
129 = 122 x 1 + 7
We consider the new divisor 122 and the new remainder 7,and apply the division lemma to get
122 = 7 x 17 + 3
We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get
7 = 3 x 2 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 380 and 251 is 1
Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(122,7) = HCF(129,122) = HCF(251,129) = HCF(380,251) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 550 > 1, we apply the division lemma to 550 and 1, to get
550 = 1 x 550 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 550 is 1
Notice that 1 = HCF(550,1) .
