HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 382, 945, 478 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 382, 945, 478 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 382, 945, 478 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 382, 945, 478 is 1.
HCF(382, 945, 478) = 1
HCF of 382, 945, 478 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 382, 945, 478 is 1.
Highest Common Factor of 382,945,478 is 1
Step 1: Since 945 > 382, we apply the division lemma to 945 and 382, to get
945 = 382 x 2 + 181
Step 2: Since the reminder 382 ≠ 0, we apply division lemma to 181 and 382, to get
382 = 181 x 2 + 20
Step 3: We consider the new divisor 181 and the new remainder 20, and apply the division lemma to get
181 = 20 x 9 + 1
We consider the new divisor 20 and the new remainder 1, and apply the division lemma to get
20 = 1 x 20 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 382 and 945 is 1
Notice that 1 = HCF(20,1) = HCF(181,20) = HCF(382,181) = HCF(945,382) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 478 > 1, we apply the division lemma to 478 and 1, to get
478 = 1 x 478 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 478 is 1
Notice that 1 = HCF(478,1) .
