HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 140, 622, 156 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 140, 622, 156 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, 622, 156 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, 622, 156 is 2.
HCF(140, 622, 156) = 2
HCF of 140, 622, 156 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, 622, 156 is 2.
Highest Common Factor of 140,622,156 is 2
Step 1: Since 622 > 140, we apply the division lemma to 622 and 140, to get
622 = 140 x 4 + 62
Step 2: Since the reminder 140 ≠ 0, we apply division lemma to 62 and 140, to get
140 = 62 x 2 + 16
Step 3: We consider the new divisor 62 and the new remainder 16, and apply the division lemma to get
62 = 16 x 3 + 14
We consider the new divisor 16 and the new remainder 14,and apply the division lemma to get
16 = 14 x 1 + 2
We consider the new divisor 14 and the new remainder 2,and apply the division lemma to get
14 = 2 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 140 and 622 is 2
Notice that 2 = HCF(14,2) = HCF(16,14) = HCF(62,16) = HCF(140,62) = HCF(622,140) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 156 > 2, we apply the division lemma to 156 and 2, to get
156 = 2 x 78 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 156 is 2
Notice that 2 = HCF(156,2) .
