HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 763, 728, 436 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 763, 728, 436 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 763, 728, 436 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 763, 728, 436 is 1.
HCF(763, 728, 436) = 1
HCF of 763, 728, 436 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 763, 728, 436 is 1.
Highest Common Factor of 763,728,436 is 1
Step 1: Since 763 > 728, we apply the division lemma to 763 and 728, to get
763 = 728 x 1 + 35
Step 2: Since the reminder 728 ≠ 0, we apply division lemma to 35 and 728, to get
728 = 35 x 20 + 28
Step 3: We consider the new divisor 35 and the new remainder 28, and apply the division lemma to get
35 = 28 x 1 + 7
We consider the new divisor 28 and the new remainder 7, and apply the division lemma to get
28 = 7 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 763 and 728 is 7
Notice that 7 = HCF(28,7) = HCF(35,28) = HCF(728,35) = HCF(763,728) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 436 > 7, we apply the division lemma to 436 and 7, to get
436 = 7 x 62 + 2
Step 2: Since the reminder 7 ≠ 0, we apply division lemma to 2 and 7, to get
7 = 2 x 3 + 1
Step 3: 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 7 and 436 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(436,7) .
