HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 616, 246, 90, 145 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 616, 246, 90, 145 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 616, 246, 90, 145 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 616, 246, 90, 145 is 1.
HCF(616, 246, 90, 145) = 1
HCF of 616, 246, 90, 145 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 616, 246, 90, 145 is 1.
Highest Common Factor of 616,246,90,145 is 1
Step 1: Since 616 > 246, we apply the division lemma to 616 and 246, to get
616 = 246 x 2 + 124
Step 2: Since the reminder 246 ≠ 0, we apply division lemma to 124 and 246, to get
246 = 124 x 1 + 122
Step 3: We consider the new divisor 124 and the new remainder 122, and apply the division lemma to get
124 = 122 x 1 + 2
We consider the new divisor 122 and the new remainder 2, and apply the division lemma to get
122 = 2 x 61 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 616 and 246 is 2
Notice that 2 = HCF(122,2) = HCF(124,122) = HCF(246,124) = HCF(616,246) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 90 > 2, we apply the division lemma to 90 and 2, to get
90 = 2 x 45 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 90 is 2
Notice that 2 = HCF(90,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 145 > 2, we apply the division lemma to 145 and 2, to get
145 = 2 x 72 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 145 is 1
Notice that 1 = HCF(2,1) = HCF(145,2) .
