Answer

LCM of 66 and 70 is 2,310

(Two thousand, three hundred ten)

Finding LCM for 66 and 70 using GCF of these numbers

The first method to find LCM for numbers 66 and 70 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 66 and 70 is 2, so

LCM = (66 × 70) ÷ 2

LCM = 4620 ÷ 2

LCM = 2310

Finding LCM for 66 and 70 by Listing Multiples

The second method to find LCM for numbers 66 and 70 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 66: 66, 132, 198, 264, 330, 396, 462, 528, 594, 660, 726, 792, 858, 924, 990, 1056, 1122, 1188, 1254, 1320, 1386, 1452, 1518, 1584, 1650, 1716, 1782, 1848, 1914, 1980, 2046, 2112, 2178, 2244, 2310, 2376, 2442

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

So the LCM for 66 and 70 is 2310

Finding LCM for 66 and 70 by Prime Factorization

Another method to find LCM for numbers 66 and 70 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 66: 2, 3, 11 (exponent form: 21, 31, 111)

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

21 × 31 × 111 × 51 × 71 = 2310
