HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 123, 448, 836 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 123, 448, 836 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 123, 448, 836 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 123, 448, 836 is 1.
HCF(123, 448, 836) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 123, 448, 836 is 1.
Step 1: Since 448 > 123, we apply the division lemma to 448 and 123, to get
448 = 123 x 3 + 79
Step 2: Since the reminder 123 ≠ 0, we apply division lemma to 79 and 123, to get
123 = 79 x 1 + 44
Step 3: We consider the new divisor 79 and the new remainder 44, and apply the division lemma to get
79 = 44 x 1 + 35
We consider the new divisor 44 and the new remainder 35,and apply the division lemma to get
44 = 35 x 1 + 9
We consider the new divisor 35 and the new remainder 9,and apply the division lemma to get
35 = 9 x 3 + 8
We consider the new divisor 9 and the new remainder 8,and apply the division lemma to get
9 = 8 x 1 + 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 123 and 448 is 1
Notice that 1 = HCF(8,1) = HCF(9,8) = HCF(35,9) = HCF(44,35) = HCF(79,44) = HCF(123,79) = HCF(448,123) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 836 > 1, we apply the division lemma to 836 and 1, to get
836 = 1 x 836 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 836 is 1
Notice that 1 = HCF(836,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
