HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 744, 549, 370 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 744, 549, 370 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 744, 549, 370 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 744, 549, 370 is 1.
HCF(744, 549, 370) = 1
HCF of 744, 549, 370 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 744, 549, 370 is 1.
Highest Common Factor of 744,549,370 is 1
Step 1: Since 744 > 549, we apply the division lemma to 744 and 549, to get
744 = 549 x 1 + 195
Step 2: Since the reminder 549 ≠ 0, we apply division lemma to 195 and 549, to get
549 = 195 x 2 + 159
Step 3: We consider the new divisor 195 and the new remainder 159, and apply the division lemma to get
195 = 159 x 1 + 36
We consider the new divisor 159 and the new remainder 36,and apply the division lemma to get
159 = 36 x 4 + 15
We consider the new divisor 36 and the new remainder 15,and apply the division lemma to get
36 = 15 x 2 + 6
We consider the new divisor 15 and the new remainder 6,and apply the division lemma to get
15 = 6 x 2 + 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 744 and 549 is 3
Notice that 3 = HCF(6,3) = HCF(15,6) = HCF(36,15) = HCF(159,36) = HCF(195,159) = HCF(549,195) = HCF(744,549) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 370 > 3, we apply the division lemma to 370 and 3, to get
370 = 3 x 123 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 370 is 1
Notice that 1 = HCF(3,1) = HCF(370,3) .
