HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 900, 125, 73 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 900, 125, 73 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 900, 125, 73 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 900, 125, 73 is 1.
HCF(900, 125, 73) = 1
HCF of 900, 125, 73 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 900, 125, 73 is 1.
Highest Common Factor of 900,125,73 is 1
Step 1: Since 900 > 125, we apply the division lemma to 900 and 125, to get
900 = 125 x 7 + 25
Step 2: Since the reminder 125 ≠ 0, we apply division lemma to 25 and 125, to get
125 = 25 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 25, the HCF of 900 and 125 is 25
Notice that 25 = HCF(125,25) = HCF(900,125) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 73 > 25, we apply the division lemma to 73 and 25, to get
73 = 25 x 2 + 23
Step 2: Since the reminder 25 ≠ 0, we apply division lemma to 23 and 25, to get
25 = 23 x 1 + 2
Step 3: We consider the new divisor 23 and the new remainder 2, and apply the division lemma to get
23 = 2 x 11 + 1
We consider the new divisor 2 and the new remainder 1, and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 25 and 73 is 1
Notice that 1 = HCF(2,1) = HCF(23,2) = HCF(25,23) = HCF(73,25) .
