HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 664, 555 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 664, 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 664, 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 664, 555 is 1.
HCF(664, 555) = 1
HCF of 664, 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 664, 555 is 1.
Highest Common Factor of 664,555 is 1
Step 1: Since 664 > 555, we apply the division lemma to 664 and 555, to get
664 = 555 x 1 + 109
Step 2: Since the reminder 555 ≠ 0, we apply division lemma to 109 and 555, to get
555 = 109 x 5 + 10
Step 3: We consider the new divisor 109 and the new remainder 10, and apply the division lemma to get
109 = 10 x 10 + 9
We consider the new divisor 10 and the new remainder 9,and apply the division lemma to get
10 = 9 x 1 + 1
We consider the new divisor 9 and the new remainder 1,and apply the division lemma to get
9 = 1 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 664 and 555 is 1
Notice that 1 = HCF(9,1) = HCF(10,9) = HCF(109,10) = HCF(555,109) = HCF(664,555) .
