HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 718, 490, 123 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 718, 490, 123 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 718, 490, 123 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 718, 490, 123 is 1.
HCF(718, 490, 123) = 1
HCF of 718, 490, 123 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 718, 490, 123 is 1.
Highest Common Factor of 718,490,123 is 1
Step 1: Since 718 > 490, we apply the division lemma to 718 and 490, to get
718 = 490 x 1 + 228
Step 2: Since the reminder 490 ≠ 0, we apply division lemma to 228 and 490, to get
490 = 228 x 2 + 34
Step 3: We consider the new divisor 228 and the new remainder 34, and apply the division lemma to get
228 = 34 x 6 + 24
We consider the new divisor 34 and the new remainder 24,and apply the division lemma to get
34 = 24 x 1 + 10
We consider the new divisor 24 and the new remainder 10,and apply the division lemma to get
24 = 10 x 2 + 4
We consider the new divisor 10 and the new remainder 4,and apply the division lemma to get
10 = 4 x 2 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 718 and 490 is 2
Notice that 2 = HCF(4,2) = HCF(10,4) = HCF(24,10) = HCF(34,24) = HCF(228,34) = HCF(490,228) = HCF(718,490) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 123 > 2, we apply the division lemma to 123 and 2, to get
123 = 2 x 61 + 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 123 is 1
Notice that 1 = HCF(2,1) = HCF(123,2) .
