HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 394, 531, 481 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 394, 531, 481 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 394, 531, 481 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 394, 531, 481 is 1.
HCF(394, 531, 481) = 1
HCF of 394, 531, 481 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 394, 531, 481 is 1.
Highest Common Factor of 394,531,481 is 1
Step 1: Since 531 > 394, we apply the division lemma to 531 and 394, to get
531 = 394 x 1 + 137
Step 2: Since the reminder 394 ≠ 0, we apply division lemma to 137 and 394, to get
394 = 137 x 2 + 120
Step 3: We consider the new divisor 137 and the new remainder 120, and apply the division lemma to get
137 = 120 x 1 + 17
We consider the new divisor 120 and the new remainder 17,and apply the division lemma to get
120 = 17 x 7 + 1
We consider the new divisor 17 and the new remainder 1,and apply the division lemma to get
17 = 1 x 17 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 394 and 531 is 1
Notice that 1 = HCF(17,1) = HCF(120,17) = HCF(137,120) = HCF(394,137) = HCF(531,394) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 481 > 1, we apply the division lemma to 481 and 1, to get
481 = 1 x 481 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 481 is 1
Notice that 1 = HCF(481,1) .
