HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 7545, 7834, 63849 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 7545, 7834, 63849 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 7545, 7834, 63849 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 7545, 7834, 63849 is 1.
HCF(7545, 7834, 63849) = 1
HCF of 7545, 7834, 63849 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 7545, 7834, 63849 is 1.
Highest Common Factor of 7545,7834,63849 is 1
Step 1: Since 7834 > 7545, we apply the division lemma to 7834 and 7545, to get
7834 = 7545 x 1 + 289
Step 2: Since the reminder 7545 ≠ 0, we apply division lemma to 289 and 7545, to get
7545 = 289 x 26 + 31
Step 3: We consider the new divisor 289 and the new remainder 31, and apply the division lemma to get
289 = 31 x 9 + 10
We consider the new divisor 31 and the new remainder 10,and apply the division lemma to get
31 = 10 x 3 + 1
We consider the new divisor 10 and the new remainder 1,and apply the division lemma to get
10 = 1 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 7545 and 7834 is 1
Notice that 1 = HCF(10,1) = HCF(31,10) = HCF(289,31) = HCF(7545,289) = HCF(7834,7545) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 63849 > 1, we apply the division lemma to 63849 and 1, to get
63849 = 1 x 63849 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 63849 is 1
Notice that 1 = HCF(63849,1) .
