HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 45, 75, 714 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 45, 75, 714 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 45, 75, 714 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 45, 75, 714 is 3.
HCF(45, 75, 714) = 3
HCF of 45, 75, 714 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 45, 75, 714 is 3.
Highest Common Factor of 45,75,714 is 3
Step 1: Since 75 > 45, we apply the division lemma to 75 and 45, to get
75 = 45 x 1 + 30
Step 2: Since the reminder 45 ≠ 0, we apply division lemma to 30 and 45, to get
45 = 30 x 1 + 15
Step 3: We consider the new divisor 30 and the new remainder 15, and apply the division lemma to get
30 = 15 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 15, the HCF of 45 and 75 is 15
Notice that 15 = HCF(30,15) = HCF(45,30) = HCF(75,45) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 714 > 15, we apply the division lemma to 714 and 15, to get
714 = 15 x 47 + 9
Step 2: Since the reminder 15 ≠ 0, we apply division lemma to 9 and 15, to get
15 = 9 x 1 + 6
Step 3: We consider the new divisor 9 and the new remainder 6, and apply the division lemma to get
9 = 6 x 1 + 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 15 and 714 is 3
Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(15,9) = HCF(714,15) .
