HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 670, 786, 150 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 670, 786, 150 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 670, 786, 150 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 670, 786, 150 is 2.
HCF(670, 786, 150) = 2
HCF of 670, 786, 150 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 670, 786, 150 is 2.
Highest Common Factor of 670,786,150 is 2
Step 1: Since 786 > 670, we apply the division lemma to 786 and 670, to get
786 = 670 x 1 + 116
Step 2: Since the reminder 670 ≠ 0, we apply division lemma to 116 and 670, to get
670 = 116 x 5 + 90
Step 3: We consider the new divisor 116 and the new remainder 90, and apply the division lemma to get
116 = 90 x 1 + 26
We consider the new divisor 90 and the new remainder 26,and apply the division lemma to get
90 = 26 x 3 + 12
We consider the new divisor 26 and the new remainder 12,and apply the division lemma to get
26 = 12 x 2 + 2
We consider the new divisor 12 and the new remainder 2,and apply the division lemma to get
12 = 2 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 670 and 786 is 2
Notice that 2 = HCF(12,2) = HCF(26,12) = HCF(90,26) = HCF(116,90) = HCF(670,116) = HCF(786,670) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 150 > 2, we apply the division lemma to 150 and 2, to get
150 = 2 x 75 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 150 is 2
Notice that 2 = HCF(150,2) .
