HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 408, 507, 142, 37 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 408, 507, 142, 37 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 408, 507, 142, 37 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 408, 507, 142, 37 is 1.
HCF(408, 507, 142, 37) = 1
HCF of 408, 507, 142, 37 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 408, 507, 142, 37 is 1.
Highest Common Factor of 408,507,142,37 is 1
Step 1: Since 507 > 408, we apply the division lemma to 507 and 408, to get
507 = 408 x 1 + 99
Step 2: Since the reminder 408 ≠ 0, we apply division lemma to 99 and 408, to get
408 = 99 x 4 + 12
Step 3: We consider the new divisor 99 and the new remainder 12, and apply the division lemma to get
99 = 12 x 8 + 3
We consider the new divisor 12 and the new remainder 3, and apply the division lemma to get
12 = 3 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 408 and 507 is 3
Notice that 3 = HCF(12,3) = HCF(99,12) = HCF(408,99) = HCF(507,408) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 142 > 3, we apply the division lemma to 142 and 3, to get
142 = 3 x 47 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 142 is 1
Notice that 1 = HCF(3,1) = HCF(142,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 37 > 1, we apply the division lemma to 37 and 1, to get
37 = 1 x 37 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 37 is 1
Notice that 1 = HCF(37,1) .
