HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 448, 651, 828, 28 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 448, 651, 828, 28 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, 651, 828, 28 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, 651, 828, 28 is 1.
HCF(448, 651, 828, 28) = 1
HCF of 448, 651, 828, 28 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, 651, 828, 28 is 1.
Highest Common Factor of 448,651,828,28 is 1
Step 1: Since 651 > 448, we apply the division lemma to 651 and 448, to get
651 = 448 x 1 + 203
Step 2: Since the reminder 448 ≠ 0, we apply division lemma to 203 and 448, to get
448 = 203 x 2 + 42
Step 3: We consider the new divisor 203 and the new remainder 42, and apply the division lemma to get
203 = 42 x 4 + 35
We consider the new divisor 42 and the new remainder 35,and apply the division lemma to get
42 = 35 x 1 + 7
We consider the new divisor 35 and the new remainder 7,and apply the division lemma to get
35 = 7 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 448 and 651 is 7
Notice that 7 = HCF(35,7) = HCF(42,35) = HCF(203,42) = HCF(448,203) = HCF(651,448) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 828 > 7, we apply the division lemma to 828 and 7, to get
828 = 7 x 118 + 2
Step 2: Since the reminder 7 ≠ 0, we apply division lemma to 2 and 7, to get
7 = 2 x 3 + 1
Step 3: 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 7 and 828 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(828,7) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 28 > 1, we apply the division lemma to 28 and 1, to get
28 = 1 x 28 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 28 is 1
Notice that 1 = HCF(28,1) .
