HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 550, 579, 421, 223 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 550, 579, 421, 223 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 550, 579, 421, 223 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 550, 579, 421, 223 is 1.
HCF(550, 579, 421, 223) = 1
HCF of 550, 579, 421, 223 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 550, 579, 421, 223 is 1.
Highest Common Factor of 550,579,421,223 is 1
Step 1: Since 579 > 550, we apply the division lemma to 579 and 550, to get
579 = 550 x 1 + 29
Step 2: Since the reminder 550 ≠ 0, we apply division lemma to 29 and 550, to get
550 = 29 x 18 + 28
Step 3: We consider the new divisor 29 and the new remainder 28, and apply the division lemma to get
29 = 28 x 1 + 1
We consider the new divisor 28 and the new remainder 1, and apply the division lemma to get
28 = 1 x 28 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 550 and 579 is 1
Notice that 1 = HCF(28,1) = HCF(29,28) = HCF(550,29) = HCF(579,550) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 421 > 1, we apply the division lemma to 421 and 1, to get
421 = 1 x 421 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 421 is 1
Notice that 1 = HCF(421,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 223 > 1, we apply the division lemma to 223 and 1, to get
223 = 1 x 223 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 223 is 1
Notice that 1 = HCF(223,1) .
