HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 520, 975, 493, 448 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 520, 975, 493, 448 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 520, 975, 493, 448 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 520, 975, 493, 448 is 1.
HCF(520, 975, 493, 448) = 1
HCF of 520, 975, 493, 448 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 520, 975, 493, 448 is 1.
Highest Common Factor of 520,975,493,448 is 1
Step 1: Since 975 > 520, we apply the division lemma to 975 and 520, to get
975 = 520 x 1 + 455
Step 2: Since the reminder 520 ≠ 0, we apply division lemma to 455 and 520, to get
520 = 455 x 1 + 65
Step 3: We consider the new divisor 455 and the new remainder 65, and apply the division lemma to get
455 = 65 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 65, the HCF of 520 and 975 is 65
Notice that 65 = HCF(455,65) = HCF(520,455) = HCF(975,520) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 493 > 65, we apply the division lemma to 493 and 65, to get
493 = 65 x 7 + 38
Step 2: Since the reminder 65 ≠ 0, we apply division lemma to 38 and 65, to get
65 = 38 x 1 + 27
Step 3: We consider the new divisor 38 and the new remainder 27, and apply the division lemma to get
38 = 27 x 1 + 11
We consider the new divisor 27 and the new remainder 11,and apply the division lemma to get
27 = 11 x 2 + 5
We consider the new divisor 11 and the new remainder 5,and apply the division lemma to get
11 = 5 x 2 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 65 and 493 is 1
Notice that 1 = HCF(5,1) = HCF(11,5) = HCF(27,11) = HCF(38,27) = HCF(65,38) = HCF(493,65) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 448 > 1, we apply the division lemma to 448 and 1, to get
448 = 1 x 448 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 448 is 1
Notice that 1 = HCF(448,1) .
