HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 444, 415, 821, 757 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 444, 415, 821, 757 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 444, 415, 821, 757 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 444, 415, 821, 757 is 1.
HCF(444, 415, 821, 757) = 1
HCF of 444, 415, 821, 757 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 444, 415, 821, 757 is 1.
Highest Common Factor of 444,415,821,757 is 1
Step 1: Since 444 > 415, we apply the division lemma to 444 and 415, to get
444 = 415 x 1 + 29
Step 2: Since the reminder 415 ≠ 0, we apply division lemma to 29 and 415, to get
415 = 29 x 14 + 9
Step 3: We consider the new divisor 29 and the new remainder 9, and apply the division lemma to get
29 = 9 x 3 + 2
We consider the new divisor 9 and the new remainder 2,and apply the division lemma to get
9 = 2 x 4 + 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 444 and 415 is 1
Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(29,9) = HCF(415,29) = HCF(444,415) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 821 > 1, we apply the division lemma to 821 and 1, to get
821 = 1 x 821 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 821 is 1
Notice that 1 = HCF(821,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 757 > 1, we apply the division lemma to 757 and 1, to get
757 = 1 x 757 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 757 is 1
Notice that 1 = HCF(757,1) .
