HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 726, 192, 921 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 726, 192, 921 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 726, 192, 921 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, 192, 921 is 3.
HCF(726, 192, 921) = 3
HCF of 726, 192, 921 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, 192, 921 is 3.
Highest Common Factor of 726,192,921 is 3
Step 1: Since 726 > 192, we apply the division lemma to 726 and 192, to get
726 = 192 x 3 + 150
Step 2: Since the reminder 192 ≠ 0, we apply division lemma to 150 and 192, to get
192 = 150 x 1 + 42
Step 3: We consider the new divisor 150 and the new remainder 42, and apply the division lemma to get
150 = 42 x 3 + 24
We consider the new divisor 42 and the new remainder 24,and apply the division lemma to get
42 = 24 x 1 + 18
We consider the new divisor 24 and the new remainder 18,and apply the division lemma to get
24 = 18 x 1 + 6
We consider the new divisor 18 and the new remainder 6,and apply the division lemma to get
18 = 6 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 726 and 192 is 6
Notice that 6 = HCF(18,6) = HCF(24,18) = HCF(42,24) = HCF(150,42) = HCF(192,150) = HCF(726,192) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 921 > 6, we apply the division lemma to 921 and 6, to get
921 = 6 x 153 + 3
Step 2: Since the reminder 6 ≠ 0, we apply division lemma to 3 and 6, 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 6 and 921 is 3
Notice that 3 = HCF(6,3) = HCF(921,6) .
