HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 30, 45, 60, 10 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 30, 45, 60, 10 is 5 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 30, 45, 60, 10 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 30, 45, 60, 10 is 5.
HCF(30, 45, 60, 10) = 5
HCF of 30, 45, 60, 10 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 30, 45, 60, 10 is 5.
Highest Common Factor of 30,45,60,10 is 5
Step 1: Since 45 > 30, we apply the division lemma to 45 and 30, to get
45 = 30 x 1 + 15
Step 2: Since the reminder 30 ≠ 0, we apply division lemma to 15 and 30, 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 30 and 45 is 15
Notice that 15 = HCF(30,15) = HCF(45,30) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 60 > 15, we apply the division lemma to 60 and 15, to get
60 = 15 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 15, the HCF of 15 and 60 is 15
Notice that 15 = HCF(60,15) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 15 > 10, we apply the division lemma to 15 and 10, to get
15 = 10 x 1 + 5
Step 2: Since the reminder 10 ≠ 0, we apply division lemma to 5 and 10, to get
10 = 5 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 15 and 10 is 5
Notice that 5 = HCF(10,5) = HCF(15,10) .
