HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 72, 18, 53, 37 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 72, 18, 53, 37 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, 18, 53, 37 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, 18, 53, 37 is 1.
HCF(72, 18, 53, 37) = 1
HCF of 72, 18, 53, 37 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, 18, 53, 37 is 1.
Highest Common Factor of 72,18,53,37 is 1
Step 1: Since 72 > 18, we apply the division lemma to 72 and 18, to get
72 = 18 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 18, the HCF of 72 and 18 is 18
Notice that 18 = HCF(72,18) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 53 > 18, we apply the division lemma to 53 and 18, to get
53 = 18 x 2 + 17
Step 2: Since the reminder 18 ≠ 0, we apply division lemma to 17 and 18, to get
18 = 17 x 1 + 1
Step 3: We consider the new divisor 17 and the new remainder 1, and apply the division lemma to get
17 = 1 x 17 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 18 and 53 is 1
Notice that 1 = HCF(17,1) = HCF(18,17) = HCF(53,18) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 37 > 1, we apply the division lemma to 37 and 1, to get
37 = 1 x 37 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 37 is 1
Notice that 1 = HCF(37,1) .
