HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 786, 286, 448, 828 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 786, 286, 448, 828 is 2 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 786, 286, 448, 828 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 786, 286, 448, 828 is 2.
HCF(786, 286, 448, 828) = 2
HCF of 786, 286, 448, 828 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 786, 286, 448, 828 is 2.
Highest Common Factor of 786,286,448,828 is 2
Step 1: Since 786 > 286, we apply the division lemma to 786 and 286, to get
786 = 286 x 2 + 214
Step 2: Since the reminder 286 ≠ 0, we apply division lemma to 214 and 286, to get
286 = 214 x 1 + 72
Step 3: We consider the new divisor 214 and the new remainder 72, and apply the division lemma to get
214 = 72 x 2 + 70
We consider the new divisor 72 and the new remainder 70,and apply the division lemma to get
72 = 70 x 1 + 2
We consider the new divisor 70 and the new remainder 2,and apply the division lemma to get
70 = 2 x 35 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 786 and 286 is 2
Notice that 2 = HCF(70,2) = HCF(72,70) = HCF(214,72) = HCF(286,214) = HCF(786,286) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 448 > 2, we apply the division lemma to 448 and 2, to get
448 = 2 x 224 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 448 is 2
Notice that 2 = HCF(448,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 828 > 2, we apply the division lemma to 828 and 2, to get
828 = 2 x 414 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 828 is 2
Notice that 2 = HCF(828,2) .
