HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 144, 652, 465 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 144, 652, 465 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 144, 652, 465 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 144, 652, 465 is 1.
HCF(144, 652, 465) = 1
HCF of 144, 652, 465 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 144, 652, 465 is 1.
Highest Common Factor of 144,652,465 is 1
Step 1: Since 652 > 144, we apply the division lemma to 652 and 144, to get
652 = 144 x 4 + 76
Step 2: Since the reminder 144 ≠ 0, we apply division lemma to 76 and 144, to get
144 = 76 x 1 + 68
Step 3: We consider the new divisor 76 and the new remainder 68, and apply the division lemma to get
76 = 68 x 1 + 8
We consider the new divisor 68 and the new remainder 8,and apply the division lemma to get
68 = 8 x 8 + 4
We consider the new divisor 8 and the new remainder 4,and apply the division lemma to get
8 = 4 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 144 and 652 is 4
Notice that 4 = HCF(8,4) = HCF(68,8) = HCF(76,68) = HCF(144,76) = HCF(652,144) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 465 > 4, we apply the division lemma to 465 and 4, to get
465 = 4 x 116 + 1
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 1 and 4, to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 4 and 465 is 1
Notice that 1 = HCF(4,1) = HCF(465,4) .
