HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 555, 356, 13 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 555, 356, 13 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, 356, 13 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, 356, 13 is 1.
HCF(555, 356, 13) = 1
HCF of 555, 356, 13 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, 356, 13 is 1.
Highest Common Factor of 555,356,13 is 1
Step 1: Since 555 > 356, we apply the division lemma to 555 and 356, to get
555 = 356 x 1 + 199
Step 2: Since the reminder 356 ≠ 0, we apply division lemma to 199 and 356, to get
356 = 199 x 1 + 157
Step 3: We consider the new divisor 199 and the new remainder 157, and apply the division lemma to get
199 = 157 x 1 + 42
We consider the new divisor 157 and the new remainder 42,and apply the division lemma to get
157 = 42 x 3 + 31
We consider the new divisor 42 and the new remainder 31,and apply the division lemma to get
42 = 31 x 1 + 11
We consider the new divisor 31 and the new remainder 11,and apply the division lemma to get
31 = 11 x 2 + 9
We consider the new divisor 11 and the new remainder 9,and apply the division lemma to get
11 = 9 x 1 + 2
We consider the new divisor 9 and the new remainder 2,and apply the division lemma to get
9 = 2 x 4 + 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 555 and 356 is 1
Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(11,9) = HCF(31,11) = HCF(42,31) = HCF(157,42) = HCF(199,157) = HCF(356,199) = HCF(555,356) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 13 > 1, we apply the division lemma to 13 and 1, to get
13 = 1 x 13 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 13 is 1
Notice that 1 = HCF(13,1) .
