HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 472, 803, 717, 450 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 472, 803, 717, 450 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 472, 803, 717, 450 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 472, 803, 717, 450 is 1.
HCF(472, 803, 717, 450) = 1
HCF of 472, 803, 717, 450 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 472, 803, 717, 450 is 1.
Highest Common Factor of 472,803,717,450 is 1
Step 1: Since 803 > 472, we apply the division lemma to 803 and 472, to get
803 = 472 x 1 + 331
Step 2: Since the reminder 472 ≠ 0, we apply division lemma to 331 and 472, to get
472 = 331 x 1 + 141
Step 3: We consider the new divisor 331 and the new remainder 141, and apply the division lemma to get
331 = 141 x 2 + 49
We consider the new divisor 141 and the new remainder 49,and apply the division lemma to get
141 = 49 x 2 + 43
We consider the new divisor 49 and the new remainder 43,and apply the division lemma to get
49 = 43 x 1 + 6
We consider the new divisor 43 and the new remainder 6,and apply the division lemma to get
43 = 6 x 7 + 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 472 and 803 is 1
Notice that 1 = HCF(6,1) = HCF(43,6) = HCF(49,43) = HCF(141,49) = HCF(331,141) = HCF(472,331) = HCF(803,472) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 717 > 1, we apply the division lemma to 717 and 1, to get
717 = 1 x 717 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 717 is 1
Notice that 1 = HCF(717,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 450 > 1, we apply the division lemma to 450 and 1, to get
450 = 1 x 450 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 450 is 1
Notice that 1 = HCF(450,1) .
