HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 72, 44, 609 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 72, 44, 609 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 72, 44, 609 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 72, 44, 609 is 1.
HCF(72, 44, 609) = 1
HCF of 72, 44, 609 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 72, 44, 609 is 1.
Highest Common Factor of 72,44,609 is 1
Step 1: Since 72 > 44, we apply the division lemma to 72 and 44, to get
72 = 44 x 1 + 28
Step 2: Since the reminder 44 ≠ 0, we apply division lemma to 28 and 44, to get
44 = 28 x 1 + 16
Step 3: We consider the new divisor 28 and the new remainder 16, and apply the division lemma to get
28 = 16 x 1 + 12
We consider the new divisor 16 and the new remainder 12,and apply the division lemma to get
16 = 12 x 1 + 4
We consider the new divisor 12 and the new remainder 4,and apply the division lemma to get
12 = 4 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 72 and 44 is 4
Notice that 4 = HCF(12,4) = HCF(16,12) = HCF(28,16) = HCF(44,28) = HCF(72,44) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 609 > 4, we apply the division lemma to 609 and 4, to get
609 = 4 x 152 + 1
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 1 and 4, to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 4 and 609 is 1
Notice that 1 = HCF(4,1) = HCF(609,4) .
