HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 453, 778, 48 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 453, 778, 48 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 453, 778, 48 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 453, 778, 48 is 1.
HCF(453, 778, 48) = 1
HCF of 453, 778, 48 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 453, 778, 48 is 1.
Highest Common Factor of 453,778,48 is 1
Step 1: Since 778 > 453, we apply the division lemma to 778 and 453, to get
778 = 453 x 1 + 325
Step 2: Since the reminder 453 ≠ 0, we apply division lemma to 325 and 453, to get
453 = 325 x 1 + 128
Step 3: We consider the new divisor 325 and the new remainder 128, and apply the division lemma to get
325 = 128 x 2 + 69
We consider the new divisor 128 and the new remainder 69,and apply the division lemma to get
128 = 69 x 1 + 59
We consider the new divisor 69 and the new remainder 59,and apply the division lemma to get
69 = 59 x 1 + 10
We consider the new divisor 59 and the new remainder 10,and apply the division lemma to get
59 = 10 x 5 + 9
We consider the new divisor 10 and the new remainder 9,and apply the division lemma to get
10 = 9 x 1 + 1
We consider the new divisor 9 and the new remainder 1,and apply the division lemma to get
9 = 1 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 453 and 778 is 1
Notice that 1 = HCF(9,1) = HCF(10,9) = HCF(59,10) = HCF(69,59) = HCF(128,69) = HCF(325,128) = HCF(453,325) = HCF(778,453) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 48 > 1, we apply the division lemma to 48 and 1, to get
48 = 1 x 48 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 48 is 1
Notice that 1 = HCF(48,1) .
