HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 900, 628, 909 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 900, 628, 909 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, 628, 909 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, 628, 909 is 1.
HCF(900, 628, 909) = 1
HCF of 900, 628, 909 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, 628, 909 is 1.
Highest Common Factor of 900,628,909 is 1
Step 1: Since 900 > 628, we apply the division lemma to 900 and 628, to get
900 = 628 x 1 + 272
Step 2: Since the reminder 628 ≠ 0, we apply division lemma to 272 and 628, to get
628 = 272 x 2 + 84
Step 3: We consider the new divisor 272 and the new remainder 84, and apply the division lemma to get
272 = 84 x 3 + 20
We consider the new divisor 84 and the new remainder 20,and apply the division lemma to get
84 = 20 x 4 + 4
We consider the new divisor 20 and the new remainder 4,and apply the division lemma to get
20 = 4 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 900 and 628 is 4
Notice that 4 = HCF(20,4) = HCF(84,20) = HCF(272,84) = HCF(628,272) = HCF(900,628) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 909 > 4, we apply the division lemma to 909 and 4, to get
909 = 4 x 227 + 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 909 is 1
Notice that 1 = HCF(4,1) = HCF(909,4) .
