HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 907, 479, 386 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 907, 479, 386 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 907, 479, 386 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 907, 479, 386 is 1.
HCF(907, 479, 386) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 907, 479, 386 is 1.
Step 1: Since 907 > 479, we apply the division lemma to 907 and 479, to get
907 = 479 x 1 + 428
Step 2: Since the reminder 479 ≠ 0, we apply division lemma to 428 and 479, to get
479 = 428 x 1 + 51
Step 3: We consider the new divisor 428 and the new remainder 51, and apply the division lemma to get
428 = 51 x 8 + 20
We consider the new divisor 51 and the new remainder 20,and apply the division lemma to get
51 = 20 x 2 + 11
We consider the new divisor 20 and the new remainder 11,and apply the division lemma to get
20 = 11 x 1 + 9
We consider the new divisor 11 and the new remainder 9,and apply the division lemma to get
11 = 9 x 1 + 2
We consider the new divisor 9 and the new remainder 2,and apply the division lemma to get
9 = 2 x 4 + 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 907 and 479 is 1
Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(11,9) = HCF(20,11) = HCF(51,20) = HCF(428,51) = HCF(479,428) = HCF(907,479) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 386 > 1, we apply the division lemma to 386 and 1, to get
386 = 1 x 386 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 386 is 1
Notice that 1 = HCF(386,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
