HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 91, 390, 884 i.e. 13 the largest integer that leaves a remainder zero for all numbers.
HCF of 91, 390, 884 is 13 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 91, 390, 884 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 91, 390, 884 is 13.
HCF(91, 390, 884) = 13
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 91, 390, 884 is 13.
Step 1: Since 390 > 91, we apply the division lemma to 390 and 91, to get
390 = 91 x 4 + 26
Step 2: Since the reminder 91 ≠ 0, we apply division lemma to 26 and 91, to get
91 = 26 x 3 + 13
Step 3: We consider the new divisor 26 and the new remainder 13, and apply the division lemma to get
26 = 13 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 13, the HCF of 91 and 390 is 13
Notice that 13 = HCF(26,13) = HCF(91,26) = HCF(390,91) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 884 > 13, we apply the division lemma to 884 and 13, to get
884 = 13 x 68 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 13, the HCF of 13 and 884 is 13
Notice that 13 = HCF(884,13) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
