HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 432, 553, 669 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 432, 553, 669 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 432, 553, 669 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 432, 553, 669 is 1.
HCF(432, 553, 669) = 1
HCF of 432, 553, 669 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 432, 553, 669 is 1.
Highest Common Factor of 432,553,669 is 1
Step 1: Since 553 > 432, we apply the division lemma to 553 and 432, to get
553 = 432 x 1 + 121
Step 2: Since the reminder 432 ≠ 0, we apply division lemma to 121 and 432, to get
432 = 121 x 3 + 69
Step 3: We consider the new divisor 121 and the new remainder 69, and apply the division lemma to get
121 = 69 x 1 + 52
We consider the new divisor 69 and the new remainder 52,and apply the division lemma to get
69 = 52 x 1 + 17
We consider the new divisor 52 and the new remainder 17,and apply the division lemma to get
52 = 17 x 3 + 1
We consider the new divisor 17 and the new remainder 1,and apply the division lemma to get
17 = 1 x 17 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 432 and 553 is 1
Notice that 1 = HCF(17,1) = HCF(52,17) = HCF(69,52) = HCF(121,69) = HCF(432,121) = HCF(553,432) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 669 > 1, we apply the division lemma to 669 and 1, to get
669 = 1 x 669 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 669 is 1
Notice that 1 = HCF(669,1) .
