HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 448, 825, 79 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 448, 825, 79 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 448, 825, 79 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 448, 825, 79 is 1.
HCF(448, 825, 79) = 1
HCF of 448, 825, 79 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 448, 825, 79 is 1.
Highest Common Factor of 448,825,79 is 1
Step 1: Since 825 > 448, we apply the division lemma to 825 and 448, to get
825 = 448 x 1 + 377
Step 2: Since the reminder 448 ≠ 0, we apply division lemma to 377 and 448, to get
448 = 377 x 1 + 71
Step 3: We consider the new divisor 377 and the new remainder 71, and apply the division lemma to get
377 = 71 x 5 + 22
We consider the new divisor 71 and the new remainder 22,and apply the division lemma to get
71 = 22 x 3 + 5
We consider the new divisor 22 and the new remainder 5,and apply the division lemma to get
22 = 5 x 4 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma 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 448 and 825 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(22,5) = HCF(71,22) = HCF(377,71) = HCF(448,377) = HCF(825,448) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 79 > 1, we apply the division lemma to 79 and 1, to get
79 = 1 x 79 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 79 is 1
Notice that 1 = HCF(79,1) .
