HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 155, 679, 440 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 155, 679, 440 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 155, 679, 440 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 155, 679, 440 is 1.
HCF(155, 679, 440) = 1
HCF of 155, 679, 440 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 155, 679, 440 is 1.
Highest Common Factor of 155,679,440 is 1
Step 1: Since 679 > 155, we apply the division lemma to 679 and 155, to get
679 = 155 x 4 + 59
Step 2: Since the reminder 155 ≠ 0, we apply division lemma to 59 and 155, to get
155 = 59 x 2 + 37
Step 3: We consider the new divisor 59 and the new remainder 37, and apply the division lemma to get
59 = 37 x 1 + 22
We consider the new divisor 37 and the new remainder 22,and apply the division lemma to get
37 = 22 x 1 + 15
We consider the new divisor 22 and the new remainder 15,and apply the division lemma to get
22 = 15 x 1 + 7
We consider the new divisor 15 and the new remainder 7,and apply the division lemma to get
15 = 7 x 2 + 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 155 and 679 is 1
Notice that 1 = HCF(7,1) = HCF(15,7) = HCF(22,15) = HCF(37,22) = HCF(59,37) = HCF(155,59) = HCF(679,155) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 440 > 1, we apply the division lemma to 440 and 1, to get
440 = 1 x 440 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 440 is 1
Notice that 1 = HCF(440,1) .
