HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 520, 552, 555 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 520, 552, 555 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, 552, 555 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, 552, 555 is 1.
HCF(520, 552, 555) = 1
HCF of 520, 552, 555 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, 552, 555 is 1.
Highest Common Factor of 520,552,555 is 1
Step 1: Since 552 > 520, we apply the division lemma to 552 and 520, to get
552 = 520 x 1 + 32
Step 2: Since the reminder 520 ≠ 0, we apply division lemma to 32 and 520, to get
520 = 32 x 16 + 8
Step 3: We consider the new divisor 32 and the new remainder 8, and apply the division lemma to get
32 = 8 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 8, the HCF of 520 and 552 is 8
Notice that 8 = HCF(32,8) = HCF(520,32) = HCF(552,520) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 555 > 8, we apply the division lemma to 555 and 8, to get
555 = 8 x 69 + 3
Step 2: Since the reminder 8 ≠ 0, we apply division lemma to 3 and 8, to get
8 = 3 x 2 + 2
Step 3: We consider the new divisor 3 and the new remainder 2, and apply the division lemma to get
3 = 2 x 1 + 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 8 and 555 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(8,3) = HCF(555,8) .
