HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 446, 809, 151, 72 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 446, 809, 151, 72 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 446, 809, 151, 72 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 446, 809, 151, 72 is 1.
HCF(446, 809, 151, 72) = 1
HCF of 446, 809, 151, 72 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 446, 809, 151, 72 is 1.
Highest Common Factor of 446,809,151,72 is 1
Step 1: Since 809 > 446, we apply the division lemma to 809 and 446, to get
809 = 446 x 1 + 363
Step 2: Since the reminder 446 ≠ 0, we apply division lemma to 363 and 446, to get
446 = 363 x 1 + 83
Step 3: We consider the new divisor 363 and the new remainder 83, and apply the division lemma to get
363 = 83 x 4 + 31
We consider the new divisor 83 and the new remainder 31,and apply the division lemma to get
83 = 31 x 2 + 21
We consider the new divisor 31 and the new remainder 21,and apply the division lemma to get
31 = 21 x 1 + 10
We consider the new divisor 21 and the new remainder 10,and apply the division lemma to get
21 = 10 x 2 + 1
We consider the new divisor 10 and the new remainder 1,and apply the division lemma to get
10 = 1 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 446 and 809 is 1
Notice that 1 = HCF(10,1) = HCF(21,10) = HCF(31,21) = HCF(83,31) = HCF(363,83) = HCF(446,363) = HCF(809,446) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 151 > 1, we apply the division lemma to 151 and 1, to get
151 = 1 x 151 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 151 is 1
Notice that 1 = HCF(151,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 72 > 1, we apply the division lemma to 72 and 1, to get
72 = 1 x 72 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 72 is 1
Notice that 1 = HCF(72,1) .
