HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 240, 552, 257 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 240, 552, 257 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 240, 552, 257 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 240, 552, 257 is 1.
HCF(240, 552, 257) = 1
HCF of 240, 552, 257 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 240, 552, 257 is 1.
Highest Common Factor of 240,552,257 is 1
Step 1: Since 552 > 240, we apply the division lemma to 552 and 240, to get
552 = 240 x 2 + 72
Step 2: Since the reminder 240 ≠ 0, we apply division lemma to 72 and 240, to get
240 = 72 x 3 + 24
Step 3: We consider the new divisor 72 and the new remainder 24, and apply the division lemma to get
72 = 24 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 24, the HCF of 240 and 552 is 24
Notice that 24 = HCF(72,24) = HCF(240,72) = HCF(552,240) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 257 > 24, we apply the division lemma to 257 and 24, to get
257 = 24 x 10 + 17
Step 2: Since the reminder 24 ≠ 0, we apply division lemma to 17 and 24, to get
24 = 17 x 1 + 7
Step 3: We consider the new divisor 17 and the new remainder 7, and apply the division lemma to get
17 = 7 x 2 + 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 24 and 257 is 1
Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(17,7) = HCF(24,17) = HCF(257,24) .
