HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 300, 842, 395, 985 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 300, 842, 395, 985 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 300, 842, 395, 985 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 300, 842, 395, 985 is 1.
HCF(300, 842, 395, 985) = 1
HCF of 300, 842, 395, 985 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 300, 842, 395, 985 is 1.
Highest Common Factor of 300,842,395,985 is 1
Step 1: Since 842 > 300, we apply the division lemma to 842 and 300, to get
842 = 300 x 2 + 242
Step 2: Since the reminder 300 ≠ 0, we apply division lemma to 242 and 300, to get
300 = 242 x 1 + 58
Step 3: We consider the new divisor 242 and the new remainder 58, and apply the division lemma to get
242 = 58 x 4 + 10
We consider the new divisor 58 and the new remainder 10,and apply the division lemma to get
58 = 10 x 5 + 8
We consider the new divisor 10 and the new remainder 8,and apply the division lemma to get
10 = 8 x 1 + 2
We consider the new divisor 8 and the new remainder 2,and apply the division lemma to get
8 = 2 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 300 and 842 is 2
Notice that 2 = HCF(8,2) = HCF(10,8) = HCF(58,10) = HCF(242,58) = HCF(300,242) = HCF(842,300) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 395 > 2, we apply the division lemma to 395 and 2, to get
395 = 2 x 197 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 395 is 1
Notice that 1 = HCF(2,1) = HCF(395,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 985 > 1, we apply the division lemma to 985 and 1, to get
985 = 1 x 985 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 985 is 1
Notice that 1 = HCF(985,1) .
