HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 653, 354, 255 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 653, 354, 255 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 653, 354, 255 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 653, 354, 255 is 1.
HCF(653, 354, 255) = 1
HCF of 653, 354, 255 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 653, 354, 255 is 1.
Highest Common Factor of 653,354,255 is 1
Step 1: Since 653 > 354, we apply the division lemma to 653 and 354, to get
653 = 354 x 1 + 299
Step 2: Since the reminder 354 ≠ 0, we apply division lemma to 299 and 354, to get
354 = 299 x 1 + 55
Step 3: We consider the new divisor 299 and the new remainder 55, and apply the division lemma to get
299 = 55 x 5 + 24
We consider the new divisor 55 and the new remainder 24,and apply the division lemma to get
55 = 24 x 2 + 7
We consider the new divisor 24 and the new remainder 7,and apply the division lemma to get
24 = 7 x 3 + 3
We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get
7 = 3 x 2 + 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 653 and 354 is 1
Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(24,7) = HCF(55,24) = HCF(299,55) = HCF(354,299) = HCF(653,354) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 255 > 1, we apply the division lemma to 255 and 1, to get
255 = 1 x 255 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 255 is 1
Notice that 1 = HCF(255,1) .
