HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 729, 375, 550 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 729, 375, 550 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 729, 375, 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 729, 375, 550 is 1.
HCF(729, 375, 550) = 1
HCF of 729, 375, 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 729, 375, 550 is 1.
Highest Common Factor of 729,375,550 is 1
Step 1: Since 729 > 375, we apply the division lemma to 729 and 375, to get
729 = 375 x 1 + 354
Step 2: Since the reminder 375 ≠ 0, we apply division lemma to 354 and 375, to get
375 = 354 x 1 + 21
Step 3: We consider the new divisor 354 and the new remainder 21, and apply the division lemma to get
354 = 21 x 16 + 18
We consider the new divisor 21 and the new remainder 18,and apply the division lemma to get
21 = 18 x 1 + 3
We consider the new divisor 18 and the new remainder 3,and apply the division lemma to get
18 = 3 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 729 and 375 is 3
Notice that 3 = HCF(18,3) = HCF(21,18) = HCF(354,21) = HCF(375,354) = HCF(729,375) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 550 > 3, we apply the division lemma to 550 and 3, to get
550 = 3 x 183 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 550 is 1
Notice that 1 = HCF(3,1) = HCF(550,3) .
