HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 740, 433, 19 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 740, 433, 19 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 740, 433, 19 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 740, 433, 19 is 1.
HCF(740, 433, 19) = 1
HCF of 740, 433, 19 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 740, 433, 19 is 1.
Highest Common Factor of 740,433,19 is 1
Step 1: Since 740 > 433, we apply the division lemma to 740 and 433, to get
740 = 433 x 1 + 307
Step 2: Since the reminder 433 ≠ 0, we apply division lemma to 307 and 433, to get
433 = 307 x 1 + 126
Step 3: We consider the new divisor 307 and the new remainder 126, and apply the division lemma to get
307 = 126 x 2 + 55
We consider the new divisor 126 and the new remainder 55,and apply the division lemma to get
126 = 55 x 2 + 16
We consider the new divisor 55 and the new remainder 16,and apply the division lemma to get
55 = 16 x 3 + 7
We consider the new divisor 16 and the new remainder 7,and apply the division lemma to get
16 = 7 x 2 + 2
We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get
7 = 2 x 3 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 740 and 433 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(16,7) = HCF(55,16) = HCF(126,55) = HCF(307,126) = HCF(433,307) = HCF(740,433) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 19 > 1, we apply the division lemma to 19 and 1, to get
19 = 1 x 19 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 19 is 1
Notice that 1 = HCF(19,1) .
