The common multiples of 21 and 28 are 84, 168, 252, 336, ... and so on, never ending; so there is no real Highest Common Multiple.
Do you mean:
Hcm of 50 and 60= 2
This question as written has no rational answer since the value of an hcm, being infinite, is unquantifiable. If you change the hcm to GCF, you could use 6 and 8 or 24 and 2.
21/28 = 3/4
1.3333
21/28 = 3/4 or 0.75
HCM Constanţa was created in 2002.
Hcm of 50 and 60= 2
HCM Roman was created in 2001.
HCM means hypertrophic cardiomyopathy
The highest common multiple is an infinite number and a bit impractical. In this case, the GCF is 7 and the LCM is 147.
The GCF is 19. The LCM is 228. The HCM is infinite.
HCM Știința Baia Mare was created in 1960.
28 times 21 equals 588.
It is: 28-21 = 7
21 out of 28 = 75%
28
