HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 305, 550 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 305, 550 is 5 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 305, 550 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 305, 550 is 5.
HCF(305, 550) = 5
HCF of 305, 550 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 305, 550 is 5.
Highest Common Factor of 305,550 is 5
Step 1: Since 550 > 305, we apply the division lemma to 550 and 305, to get
550 = 305 x 1 + 245
Step 2: Since the reminder 305 ≠ 0, we apply division lemma to 245 and 305, to get
305 = 245 x 1 + 60
Step 3: We consider the new divisor 245 and the new remainder 60, and apply the division lemma to get
245 = 60 x 4 + 5
We consider the new divisor 60 and the new remainder 5, and apply the division lemma to get
60 = 5 x 12 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 305 and 550 is 5
Notice that 5 = HCF(60,5) = HCF(245,60) = HCF(305,245) = HCF(550,305) .
