HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 249, 979, 294 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 249, 979, 294 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 249, 979, 294 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 249, 979, 294 is 1.
HCF(249, 979, 294) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 249, 979, 294 is 1.
Step 1: Since 979 > 249, we apply the division lemma to 979 and 249, to get
979 = 249 x 3 + 232
Step 2: Since the reminder 249 ≠ 0, we apply division lemma to 232 and 249, to get
249 = 232 x 1 + 17
Step 3: We consider the new divisor 232 and the new remainder 17, and apply the division lemma to get
232 = 17 x 13 + 11
We consider the new divisor 17 and the new remainder 11,and apply the division lemma to get
17 = 11 x 1 + 6
We consider the new divisor 11 and the new remainder 6,and apply the division lemma to get
11 = 6 x 1 + 5
We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get
6 = 5 x 1 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 249 and 979 is 1
Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(11,6) = HCF(17,11) = HCF(232,17) = HCF(249,232) = HCF(979,249) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 294 > 1, we apply the division lemma to 294 and 1, to get
294 = 1 x 294 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 294 is 1
Notice that 1 = HCF(294,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
