HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 972, 558, 130 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 972, 558, 130 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 972, 558, 130 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 972, 558, 130 is 2.
HCF(972, 558, 130) = 2
HCF of 972, 558, 130 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 972, 558, 130 is 2.
Highest Common Factor of 972,558,130 is 2
Step 1: Since 972 > 558, we apply the division lemma to 972 and 558, to get
972 = 558 x 1 + 414
Step 2: Since the reminder 558 ≠ 0, we apply division lemma to 414 and 558, to get
558 = 414 x 1 + 144
Step 3: We consider the new divisor 414 and the new remainder 144, and apply the division lemma to get
414 = 144 x 2 + 126
We consider the new divisor 144 and the new remainder 126,and apply the division lemma to get
144 = 126 x 1 + 18
We consider the new divisor 126 and the new remainder 18,and apply the division lemma to get
126 = 18 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 18, the HCF of 972 and 558 is 18
Notice that 18 = HCF(126,18) = HCF(144,126) = HCF(414,144) = HCF(558,414) = HCF(972,558) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 130 > 18, we apply the division lemma to 130 and 18, to get
130 = 18 x 7 + 4
Step 2: Since the reminder 18 ≠ 0, we apply division lemma to 4 and 18, to get
18 = 4 x 4 + 2
Step 3: We consider the new divisor 4 and the new remainder 2, and apply the division lemma 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 18 and 130 is 2
Notice that 2 = HCF(4,2) = HCF(18,4) = HCF(130,18) .
