HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 555, 641, 297 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 555, 641, 297 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 555, 641, 297 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 555, 641, 297 is 1.
HCF(555, 641, 297) = 1
HCF of 555, 641, 297 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 555, 641, 297 is 1.
Highest Common Factor of 555,641,297 is 1
Step 1: Since 641 > 555, we apply the division lemma to 641 and 555, to get
641 = 555 x 1 + 86
Step 2: Since the reminder 555 ≠ 0, we apply division lemma to 86 and 555, to get
555 = 86 x 6 + 39
Step 3: We consider the new divisor 86 and the new remainder 39, and apply the division lemma to get
86 = 39 x 2 + 8
We consider the new divisor 39 and the new remainder 8,and apply the division lemma to get
39 = 8 x 4 + 7
We consider the new divisor 8 and the new remainder 7,and apply the division lemma to get
8 = 7 x 1 + 1
We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 555 and 641 is 1
Notice that 1 = HCF(7,1) = HCF(8,7) = HCF(39,8) = HCF(86,39) = HCF(555,86) = HCF(641,555) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 297 > 1, we apply the division lemma to 297 and 1, to get
297 = 1 x 297 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 297 is 1
Notice that 1 = HCF(297,1) .
