HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 505, 322, 381 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 505, 322, 381 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 505, 322, 381 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 505, 322, 381 is 1.
HCF(505, 322, 381) = 1
HCF of 505, 322, 381 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 505, 322, 381 is 1.
Highest Common Factor of 505,322,381 is 1
Step 1: Since 505 > 322, we apply the division lemma to 505 and 322, to get
505 = 322 x 1 + 183
Step 2: Since the reminder 322 ≠ 0, we apply division lemma to 183 and 322, to get
322 = 183 x 1 + 139
Step 3: We consider the new divisor 183 and the new remainder 139, and apply the division lemma to get
183 = 139 x 1 + 44
We consider the new divisor 139 and the new remainder 44,and apply the division lemma to get
139 = 44 x 3 + 7
We consider the new divisor 44 and the new remainder 7,and apply the division lemma to get
44 = 7 x 6 + 2
We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get
7 = 2 x 3 + 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 505 and 322 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(44,7) = HCF(139,44) = HCF(183,139) = HCF(322,183) = HCF(505,322) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 381 > 1, we apply the division lemma to 381 and 1, to get
381 = 1 x 381 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 381 is 1
Notice that 1 = HCF(381,1) .
