HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 390, 93873 i.e. 39 the largest integer that leaves a remainder zero for all numbers.
HCF of 390, 93873 is 39 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 390, 93873 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 390, 93873 is 39.
HCF(390, 93873) = 39
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 390, 93873 is 39.
Step 1: Since 93873 > 390, we apply the division lemma to 93873 and 390, to get
93873 = 390 x 240 + 273
Step 2: Since the reminder 390 ≠ 0, we apply division lemma to 273 and 390, to get
390 = 273 x 1 + 117
Step 3: We consider the new divisor 273 and the new remainder 117, and apply the division lemma to get
273 = 117 x 2 + 39
We consider the new divisor 117 and the new remainder 39, and apply the division lemma to get
117 = 39 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 39, the HCF of 390 and 93873 is 39
Notice that 39 = HCF(117,39) = HCF(273,117) = HCF(390,273) = HCF(93873,390) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
