HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 748, 433, 73 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 748, 433, 73 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 748, 433, 73 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 748, 433, 73 is 1.
HCF(748, 433, 73) = 1
HCF of 748, 433, 73 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 748, 433, 73 is 1.
Highest Common Factor of 748,433,73 is 1
Step 1: Since 748 > 433, we apply the division lemma to 748 and 433, to get
748 = 433 x 1 + 315
Step 2: Since the reminder 433 ≠ 0, we apply division lemma to 315 and 433, to get
433 = 315 x 1 + 118
Step 3: We consider the new divisor 315 and the new remainder 118, and apply the division lemma to get
315 = 118 x 2 + 79
We consider the new divisor 118 and the new remainder 79,and apply the division lemma to get
118 = 79 x 1 + 39
We consider the new divisor 79 and the new remainder 39,and apply the division lemma to get
79 = 39 x 2 + 1
We consider the new divisor 39 and the new remainder 1,and apply the division lemma to get
39 = 1 x 39 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 748 and 433 is 1
Notice that 1 = HCF(39,1) = HCF(79,39) = HCF(118,79) = HCF(315,118) = HCF(433,315) = HCF(748,433) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 73 > 1, we apply the division lemma to 73 and 1, to get
73 = 1 x 73 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 73 is 1
Notice that 1 = HCF(73,1) .
