HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 414, 245, 123 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 414, 245, 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 414, 245, 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 414, 245, 123 is 1.
HCF(414, 245, 123) = 1
HCF of 414, 245, 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 414, 245, 123 is 1.
Highest Common Factor of 414,245,123 is 1
Step 1: Since 414 > 245, we apply the division lemma to 414 and 245, to get
414 = 245 x 1 + 169
Step 2: Since the reminder 245 ≠ 0, we apply division lemma to 169 and 245, to get
245 = 169 x 1 + 76
Step 3: We consider the new divisor 169 and the new remainder 76, and apply the division lemma to get
169 = 76 x 2 + 17
We consider the new divisor 76 and the new remainder 17,and apply the division lemma to get
76 = 17 x 4 + 8
We consider the new divisor 17 and the new remainder 8,and apply the division lemma to get
17 = 8 x 2 + 1
We consider the new divisor 8 and the new remainder 1,and apply the division lemma to get
8 = 1 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 414 and 245 is 1
Notice that 1 = HCF(8,1) = HCF(17,8) = HCF(76,17) = HCF(169,76) = HCF(245,169) = HCF(414,245) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 123 > 1, we apply the division lemma to 123 and 1, to get
123 = 1 x 123 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 123 is 1
Notice that 1 = HCF(123,1) .
