HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 723, 93681 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 723, 93681 is 3 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 723, 93681 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 723, 93681 is 3.
HCF(723, 93681) = 3
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 723, 93681 is 3.
Step 1: Since 93681 > 723, we apply the division lemma to 93681 and 723, to get
93681 = 723 x 129 + 414
Step 2: Since the reminder 723 ≠ 0, we apply division lemma to 414 and 723, to get
723 = 414 x 1 + 309
Step 3: We consider the new divisor 414 and the new remainder 309, and apply the division lemma to get
414 = 309 x 1 + 105
We consider the new divisor 309 and the new remainder 105,and apply the division lemma to get
309 = 105 x 2 + 99
We consider the new divisor 105 and the new remainder 99,and apply the division lemma to get
105 = 99 x 1 + 6
We consider the new divisor 99 and the new remainder 6,and apply the division lemma to get
99 = 6 x 16 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 723 and 93681 is 3
Notice that 3 = HCF(6,3) = HCF(99,6) = HCF(105,99) = HCF(309,105) = HCF(414,309) = HCF(723,414) = HCF(93681,723) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
