HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 752, 520, 451, 79 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 752, 520, 451, 79 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 752, 520, 451, 79 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 752, 520, 451, 79 is 1.
HCF(752, 520, 451, 79) = 1
HCF of 752, 520, 451, 79 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 752, 520, 451, 79 is 1.
Highest Common Factor of 752,520,451,79 is 1
Step 1: Since 752 > 520, we apply the division lemma to 752 and 520, to get
752 = 520 x 1 + 232
Step 2: Since the reminder 520 ≠ 0, we apply division lemma to 232 and 520, to get
520 = 232 x 2 + 56
Step 3: We consider the new divisor 232 and the new remainder 56, and apply the division lemma to get
232 = 56 x 4 + 8
We consider the new divisor 56 and the new remainder 8, and apply the division lemma to get
56 = 8 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 8, the HCF of 752 and 520 is 8
Notice that 8 = HCF(56,8) = HCF(232,56) = HCF(520,232) = HCF(752,520) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 451 > 8, we apply the division lemma to 451 and 8, to get
451 = 8 x 56 + 3
Step 2: Since the reminder 8 ≠ 0, we apply division lemma to 3 and 8, to get
8 = 3 x 2 + 2
Step 3: We consider the new divisor 3 and the new remainder 2, and apply the division lemma to get
3 = 2 x 1 + 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 8 and 451 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(8,3) = HCF(451,8) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 79 > 1, we apply the division lemma to 79 and 1, to get
79 = 1 x 79 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 79 is 1
Notice that 1 = HCF(79,1) .
