HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 535, 147, 40 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 535, 147, 40 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 535, 147, 40 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 535, 147, 40 is 1.
HCF(535, 147, 40) = 1
HCF of 535, 147, 40 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 535, 147, 40 is 1.
Highest Common Factor of 535,147,40 is 1
Step 1: Since 535 > 147, we apply the division lemma to 535 and 147, to get
535 = 147 x 3 + 94
Step 2: Since the reminder 147 ≠ 0, we apply division lemma to 94 and 147, to get
147 = 94 x 1 + 53
Step 3: We consider the new divisor 94 and the new remainder 53, and apply the division lemma to get
94 = 53 x 1 + 41
We consider the new divisor 53 and the new remainder 41,and apply the division lemma to get
53 = 41 x 1 + 12
We consider the new divisor 41 and the new remainder 12,and apply the division lemma to get
41 = 12 x 3 + 5
We consider the new divisor 12 and the new remainder 5,and apply the division lemma to get
12 = 5 x 2 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 1
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 535 and 147 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(12,5) = HCF(41,12) = HCF(53,41) = HCF(94,53) = HCF(147,94) = HCF(535,147) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 40 > 1, we apply the division lemma to 40 and 1, to get
40 = 1 x 40 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 40 is 1
Notice that 1 = HCF(40,1) .
