HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 453, 777, 230 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 453, 777, 230 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, 777, 230 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, 777, 230 is 1.
HCF(453, 777, 230) = 1
HCF of 453, 777, 230 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, 777, 230 is 1.
Highest Common Factor of 453,777,230 is 1
Step 1: Since 777 > 453, we apply the division lemma to 777 and 453, to get
777 = 453 x 1 + 324
Step 2: Since the reminder 453 ≠ 0, we apply division lemma to 324 and 453, to get
453 = 324 x 1 + 129
Step 3: We consider the new divisor 324 and the new remainder 129, and apply the division lemma to get
324 = 129 x 2 + 66
We consider the new divisor 129 and the new remainder 66,and apply the division lemma to get
129 = 66 x 1 + 63
We consider the new divisor 66 and the new remainder 63,and apply the division lemma to get
66 = 63 x 1 + 3
We consider the new divisor 63 and the new remainder 3,and apply the division lemma to get
63 = 3 x 21 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 453 and 777 is 3
Notice that 3 = HCF(63,3) = HCF(66,63) = HCF(129,66) = HCF(324,129) = HCF(453,324) = HCF(777,453) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 230 > 3, we apply the division lemma to 230 and 3, to get
230 = 3 x 76 + 2
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get
3 = 2 x 1 + 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 3 and 230 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(230,3) .
