HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 140, 492, 30, 684 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 140, 492, 30, 684 is 2 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 140, 492, 30, 684 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 140, 492, 30, 684 is 2.
HCF(140, 492, 30, 684) = 2
HCF of 140, 492, 30, 684 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 140, 492, 30, 684 is 2.
Highest Common Factor of 140,492,30,684 is 2
Step 1: Since 492 > 140, we apply the division lemma to 492 and 140, to get
492 = 140 x 3 + 72
Step 2: Since the reminder 140 ≠ 0, we apply division lemma to 72 and 140, to get
140 = 72 x 1 + 68
Step 3: We consider the new divisor 72 and the new remainder 68, and apply the division lemma to get
72 = 68 x 1 + 4
We consider the new divisor 68 and the new remainder 4, and apply the division lemma to get
68 = 4 x 17 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 140 and 492 is 4
Notice that 4 = HCF(68,4) = HCF(72,68) = HCF(140,72) = HCF(492,140) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 30 > 4, we apply the division lemma to 30 and 4, to get
30 = 4 x 7 + 2
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 2 and 4, to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 4 and 30 is 2
Notice that 2 = HCF(4,2) = HCF(30,4) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 684 > 2, we apply the division lemma to 684 and 2, to get
684 = 2 x 342 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 684 is 2
Notice that 2 = HCF(684,2) .
