HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 752, 496, 45, 455 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 752, 496, 45, 455 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 752, 496, 45, 455 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 752, 496, 45, 455 is 1.
HCF(752, 496, 45, 455) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 752, 496, 45, 455 is 1.
Step 1: Since 752 > 496, we apply the division lemma to 752 and 496, to get
752 = 496 x 1 + 256
Step 2: Since the reminder 496 ≠ 0, we apply division lemma to 256 and 496, to get
496 = 256 x 1 + 240
Step 3: We consider the new divisor 256 and the new remainder 240, and apply the division lemma to get
256 = 240 x 1 + 16
We consider the new divisor 240 and the new remainder 16, and apply the division lemma to get
240 = 16 x 15 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 16, the HCF of 752 and 496 is 16
Notice that 16 = HCF(240,16) = HCF(256,240) = HCF(496,256) = HCF(752,496) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 45 > 16, we apply the division lemma to 45 and 16, to get
45 = 16 x 2 + 13
Step 2: Since the reminder 16 ≠ 0, we apply division lemma to 13 and 16, to get
16 = 13 x 1 + 3
Step 3: We consider the new divisor 13 and the new remainder 3, and apply the division lemma to get
13 = 3 x 4 + 1
We consider the new divisor 3 and the new remainder 1, and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 16 and 45 is 1
Notice that 1 = HCF(3,1) = HCF(13,3) = HCF(16,13) = HCF(45,16) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 455 > 1, we apply the division lemma to 455 and 1, to get
455 = 1 x 455 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 455 is 1
Notice that 1 = HCF(455,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
