HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 943, 555 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 943, 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 943, 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 943, 555 is 1.
HCF(943, 555) = 1
HCF of 943, 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 943, 555 is 1.
Highest Common Factor of 943,555 is 1
Step 1: Since 943 > 555, we apply the division lemma to 943 and 555, to get
943 = 555 x 1 + 388
Step 2: Since the reminder 555 ≠ 0, we apply division lemma to 388 and 555, to get
555 = 388 x 1 + 167
Step 3: We consider the new divisor 388 and the new remainder 167, and apply the division lemma to get
388 = 167 x 2 + 54
We consider the new divisor 167 and the new remainder 54,and apply the division lemma to get
167 = 54 x 3 + 5
We consider the new divisor 54 and the new remainder 5,and apply the division lemma to get
54 = 5 x 10 + 4
We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get
5 = 4 x 1 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 943 and 555 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(54,5) = HCF(167,54) = HCF(388,167) = HCF(555,388) = HCF(943,555) .
