HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 558, 982, 979 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 558, 982, 979 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 558, 982, 979 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 558, 982, 979 is 1.
HCF(558, 982, 979) = 1
HCF of 558, 982, 979 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 558, 982, 979 is 1.
Highest Common Factor of 558,982,979 is 1
Step 1: Since 982 > 558, we apply the division lemma to 982 and 558, to get
982 = 558 x 1 + 424
Step 2: Since the reminder 558 ≠ 0, we apply division lemma to 424 and 558, to get
558 = 424 x 1 + 134
Step 3: We consider the new divisor 424 and the new remainder 134, and apply the division lemma to get
424 = 134 x 3 + 22
We consider the new divisor 134 and the new remainder 22,and apply the division lemma to get
134 = 22 x 6 + 2
We consider the new divisor 22 and the new remainder 2,and apply the division lemma to get
22 = 2 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 558 and 982 is 2
Notice that 2 = HCF(22,2) = HCF(134,22) = HCF(424,134) = HCF(558,424) = HCF(982,558) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 979 > 2, we apply the division lemma to 979 and 2, to get
979 = 2 x 489 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 979 is 1
Notice that 1 = HCF(2,1) = HCF(979,2) .
