HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 726, 643, 141 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 726, 643, 141 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 726, 643, 141 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 726, 643, 141 is 1.
HCF(726, 643, 141) = 1
HCF of 726, 643, 141 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 726, 643, 141 is 1.
Highest Common Factor of 726,643,141 is 1
Step 1: Since 726 > 643, we apply the division lemma to 726 and 643, to get
726 = 643 x 1 + 83
Step 2: Since the reminder 643 ≠ 0, we apply division lemma to 83 and 643, to get
643 = 83 x 7 + 62
Step 3: We consider the new divisor 83 and the new remainder 62, and apply the division lemma to get
83 = 62 x 1 + 21
We consider the new divisor 62 and the new remainder 21,and apply the division lemma to get
62 = 21 x 2 + 20
We consider the new divisor 21 and the new remainder 20,and apply the division lemma to get
21 = 20 x 1 + 1
We consider the new divisor 20 and the new remainder 1,and apply the division lemma to get
20 = 1 x 20 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 726 and 643 is 1
Notice that 1 = HCF(20,1) = HCF(21,20) = HCF(62,21) = HCF(83,62) = HCF(643,83) = HCF(726,643) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 141 > 1, we apply the division lemma to 141 and 1, to get
141 = 1 x 141 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 141 is 1
Notice that 1 = HCF(141,1) .
