HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 558, 355 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 558, 355 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 558, 355 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 558, 355 is 1.
HCF(558, 355) = 1
HCF of 558, 355 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 558, 355 is 1.
Highest Common Factor of 558,355 is 1
Step 1: Since 558 > 355, we apply the division lemma to 558 and 355, to get
558 = 355 x 1 + 203
Step 2: Since the reminder 355 ≠ 0, we apply division lemma to 203 and 355, to get
355 = 203 x 1 + 152
Step 3: We consider the new divisor 203 and the new remainder 152, and apply the division lemma to get
203 = 152 x 1 + 51
We consider the new divisor 152 and the new remainder 51,and apply the division lemma to get
152 = 51 x 2 + 50
We consider the new divisor 51 and the new remainder 50,and apply the division lemma to get
51 = 50 x 1 + 1
We consider the new divisor 50 and the new remainder 1,and apply the division lemma to get
50 = 1 x 50 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 558 and 355 is 1
Notice that 1 = HCF(50,1) = HCF(51,50) = HCF(152,51) = HCF(203,152) = HCF(355,203) = HCF(558,355) .
