HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 660, 748, 924, 451 i.e. 11 the largest integer that leaves a remainder zero for all numbers.
HCF of 660, 748, 924, 451 is 11 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 660, 748, 924, 451 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 660, 748, 924, 451 is 11.
HCF(660, 748, 924, 451) = 11
HCF of 660, 748, 924, 451 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 660, 748, 924, 451 is 11.
Highest Common Factor of 660,748,924,451 is 11
Step 1: Since 748 > 660, we apply the division lemma to 748 and 660, to get
748 = 660 x 1 + 88
Step 2: Since the reminder 660 ≠ 0, we apply division lemma to 88 and 660, to get
660 = 88 x 7 + 44
Step 3: We consider the new divisor 88 and the new remainder 44, and apply the division lemma to get
88 = 44 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 44, the HCF of 660 and 748 is 44
Notice that 44 = HCF(88,44) = HCF(660,88) = HCF(748,660) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 924 > 44, we apply the division lemma to 924 and 44, to get
924 = 44 x 21 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 44, the HCF of 44 and 924 is 44
Notice that 44 = HCF(924,44) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 451 > 44, we apply the division lemma to 451 and 44, to get
451 = 44 x 10 + 11
Step 2: Since the reminder 44 ≠ 0, we apply division lemma to 11 and 44, to get
44 = 11 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 11, the HCF of 44 and 451 is 11
Notice that 11 = HCF(44,11) = HCF(451,44) .
