HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 624, 451, 225 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 624, 451, 225 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 624, 451, 225 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 624, 451, 225 is 1.
HCF(624, 451, 225) = 1
HCF of 624, 451, 225 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 624, 451, 225 is 1.
Highest Common Factor of 624,451,225 is 1
Step 1: Since 624 > 451, we apply the division lemma to 624 and 451, to get
624 = 451 x 1 + 173
Step 2: Since the reminder 451 ≠ 0, we apply division lemma to 173 and 451, to get
451 = 173 x 2 + 105
Step 3: We consider the new divisor 173 and the new remainder 105, and apply the division lemma to get
173 = 105 x 1 + 68
We consider the new divisor 105 and the new remainder 68,and apply the division lemma to get
105 = 68 x 1 + 37
We consider the new divisor 68 and the new remainder 37,and apply the division lemma to get
68 = 37 x 1 + 31
We consider the new divisor 37 and the new remainder 31,and apply the division lemma to get
37 = 31 x 1 + 6
We consider the new divisor 31 and the new remainder 6,and apply the division lemma to get
31 = 6 x 5 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 624 and 451 is 1
Notice that 1 = HCF(6,1) = HCF(31,6) = HCF(37,31) = HCF(68,37) = HCF(105,68) = HCF(173,105) = HCF(451,173) = HCF(624,451) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 225 > 1, we apply the division lemma to 225 and 1, to get
225 = 1 x 225 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 225 is 1
Notice that 1 = HCF(225,1) .
