HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 923, 489, 298 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 923, 489, 298 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 923, 489, 298 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 923, 489, 298 is 1.
HCF(923, 489, 298) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 923, 489, 298 is 1.
Step 1: Since 923 > 489, we apply the division lemma to 923 and 489, to get
923 = 489 x 1 + 434
Step 2: Since the reminder 489 ≠ 0, we apply division lemma to 434 and 489, to get
489 = 434 x 1 + 55
Step 3: We consider the new divisor 434 and the new remainder 55, and apply the division lemma to get
434 = 55 x 7 + 49
We consider the new divisor 55 and the new remainder 49,and apply the division lemma to get
55 = 49 x 1 + 6
We consider the new divisor 49 and the new remainder 6,and apply the division lemma to get
49 = 6 x 8 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 923 and 489 is 1
Notice that 1 = HCF(6,1) = HCF(49,6) = HCF(55,49) = HCF(434,55) = HCF(489,434) = HCF(923,489) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 298 > 1, we apply the division lemma to 298 and 1, to get
298 = 1 x 298 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 298 is 1
Notice that 1 = HCF(298,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
