HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 456, 560, 151 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 456, 560, 151 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 456, 560, 151 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 456, 560, 151 is 1.
HCF(456, 560, 151) = 1
HCF of 456, 560, 151 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 456, 560, 151 is 1.
Highest Common Factor of 456,560,151 is 1
Step 1: Since 560 > 456, we apply the division lemma to 560 and 456, to get
560 = 456 x 1 + 104
Step 2: Since the reminder 456 ≠ 0, we apply division lemma to 104 and 456, to get
456 = 104 x 4 + 40
Step 3: We consider the new divisor 104 and the new remainder 40, and apply the division lemma to get
104 = 40 x 2 + 24
We consider the new divisor 40 and the new remainder 24,and apply the division lemma to get
40 = 24 x 1 + 16
We consider the new divisor 24 and the new remainder 16,and apply the division lemma to get
24 = 16 x 1 + 8
We consider the new divisor 16 and the new remainder 8,and apply the division lemma to get
16 = 8 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 8, the HCF of 456 and 560 is 8
Notice that 8 = HCF(16,8) = HCF(24,16) = HCF(40,24) = HCF(104,40) = HCF(456,104) = HCF(560,456) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 151 > 8, we apply the division lemma to 151 and 8, to get
151 = 8 x 18 + 7
Step 2: Since the reminder 8 ≠ 0, we apply division lemma to 7 and 8, to get
8 = 7 x 1 + 1
Step 3: We consider the new divisor 7 and the new remainder 1, and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 8 and 151 is 1
Notice that 1 = HCF(7,1) = HCF(8,7) = HCF(151,8) .
