HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 473, 860, 392 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 473, 860, 392 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 473, 860, 392 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 473, 860, 392 is 1.
HCF(473, 860, 392) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 473, 860, 392 is 1.
Step 1: Since 860 > 473, we apply the division lemma to 860 and 473, to get
860 = 473 x 1 + 387
Step 2: Since the reminder 473 ≠ 0, we apply division lemma to 387 and 473, to get
473 = 387 x 1 + 86
Step 3: We consider the new divisor 387 and the new remainder 86, and apply the division lemma to get
387 = 86 x 4 + 43
We consider the new divisor 86 and the new remainder 43, and apply the division lemma to get
86 = 43 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 43, the HCF of 473 and 860 is 43
Notice that 43 = HCF(86,43) = HCF(387,86) = HCF(473,387) = HCF(860,473) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 392 > 43, we apply the division lemma to 392 and 43, to get
392 = 43 x 9 + 5
Step 2: Since the reminder 43 ≠ 0, we apply division lemma to 5 and 43, to get
43 = 5 x 8 + 3
Step 3: We consider the new divisor 5 and the new remainder 3, and apply the division lemma to get
5 = 3 x 1 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 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 43 and 392 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(43,5) = HCF(392,43) .
Here are some samples of HCF using Euclid's Algorithm calculations.
