HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 569, 918, 144 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 569, 918, 144 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 569, 918, 144 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 569, 918, 144 is 1.
HCF(569, 918, 144) = 1
HCF of 569, 918, 144 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 569, 918, 144 is 1.
Highest Common Factor of 569,918,144 is 1
Step 1: Since 918 > 569, we apply the division lemma to 918 and 569, to get
918 = 569 x 1 + 349
Step 2: Since the reminder 569 ≠ 0, we apply division lemma to 349 and 569, to get
569 = 349 x 1 + 220
Step 3: We consider the new divisor 349 and the new remainder 220, and apply the division lemma to get
349 = 220 x 1 + 129
We consider the new divisor 220 and the new remainder 129,and apply the division lemma to get
220 = 129 x 1 + 91
We consider the new divisor 129 and the new remainder 91,and apply the division lemma to get
129 = 91 x 1 + 38
We consider the new divisor 91 and the new remainder 38,and apply the division lemma to get
91 = 38 x 2 + 15
We consider the new divisor 38 and the new remainder 15,and apply the division lemma to get
38 = 15 x 2 + 8
We consider the new divisor 15 and the new remainder 8,and apply the division lemma to get
15 = 8 x 1 + 7
We consider the new divisor 8 and the new remainder 7,and apply the division lemma to get
8 = 7 x 1 + 1
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 569 and 918 is 1
Notice that 1 = HCF(7,1) = HCF(8,7) = HCF(15,8) = HCF(38,15) = HCF(91,38) = HCF(129,91) = HCF(220,129) = HCF(349,220) = HCF(569,349) = HCF(918,569) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 144 > 1, we apply the division lemma to 144 and 1, to get
144 = 1 x 144 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 144 is 1
Notice that 1 = HCF(144,1) .
