HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 741, 144, 306 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 741, 144, 306 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 741, 144, 306 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 741, 144, 306 is 3.
HCF(741, 144, 306) = 3
HCF of 741, 144, 306 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 741, 144, 306 is 3.
Highest Common Factor of 741,144,306 is 3
Step 1: Since 741 > 144, we apply the division lemma to 741 and 144, to get
741 = 144 x 5 + 21
Step 2: Since the reminder 144 ≠ 0, we apply division lemma to 21 and 144, to get
144 = 21 x 6 + 18
Step 3: We consider the new divisor 21 and the new remainder 18, and apply the division lemma to get
21 = 18 x 1 + 3
We consider the new divisor 18 and the new remainder 3, and apply the division lemma to get
18 = 3 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 741 and 144 is 3
Notice that 3 = HCF(18,3) = HCF(21,18) = HCF(144,21) = HCF(741,144) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 306 > 3, we apply the division lemma to 306 and 3, to get
306 = 3 x 102 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 306 is 3
Notice that 3 = HCF(306,3) .
