What's the Least Common Multiple (LCM) of 70 and 305?

Answer

LCM of 70 and 305 is 4,270

(Four thousand, two hundred seventy)

Finding LCM for 70 and 305 using GCF of these numbers

The first method to find LCM for numbers 70 and 305 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 70 and 305 is 5, so

LCM = (70 × 305) ÷ 5

LCM = 21350 ÷ 5

LCM = 4270

Finding LCM for 70 and 305 by Listing Multiples

The second method to find LCM for numbers 70 and 305 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 70: 70, 140, 210, 280, 350, 420, 490, 560, 630, 700, 770, 840, 910, 980, 1050, 1120, 1190, 1260, 1330, 1400, 1470, 1540, 1610, 1680, 1750, 1820, 1890, 1960, 2030, 2100, 2170, 2240, 2310, 2380, 2450, 2520, 2590, 2660, 2730, 2800, 2870, 2940, 3010, 3080, 3150, 3220, 3290, 3360, 3430, 3500, 3570, 3640, 3710, 3780, 3850, 3920, 3990, 4060, 4130, 4200, 4270, 4340, 4410

Multiples of 305: 305, 610, 915, 1220, 1525, 1830, 2135, 2440, 2745, 3050, 3355, 3660, 3965, 4270, 4575, 4880

So the LCM for 70 and 305 is 4270

Finding LCM for 70 and 305 by Prime Factorization

Another method to find LCM for numbers 70 and 305 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 70: 2, 5, 7 (exponent form: 21, 51, 71)

All Prime Factors of 305: 5, 61 (exponent form: 51, 611)

21 × 51 × 71 × 611 = 4270
